.SH NAME
mintty \(en Cygwin terminal emulator
.SH SYNOPSIS
\fBmintty\fP [\fIOPTION\fP]... [ \fB-\fP | \fIPROGRAM\fP [\fIARG\fP]... ]
.SH DESCRIPTION
\fBMintty\fP is a terminal emulator for Cygwin with a native Windows user
interface and minimalist design.
Its terminal emulation is largely compatible with \fBxterm\fP, but it does not
require an X server.
.SH INVOCATION
If a program name is supplied on the command line, this is executed with any
additional arguments given.
Otherwise, mintty looks for a shell to execute in the \fISHELL\fP environment
variable.
If that is not set, it reads the user's default shell setting from
\fI/etc/passwd\fP.
As a last resort, it falls back to \fI/bin/sh\fP.
If a single dash is specified instead of a program name, the shell is invoked
as a login shell.
.SH OPTIONS
The standard GNU option formats are accepted, with single dashes
introducing short options and double dashes introducing long options.
.TP
\fB-c\fP, \fB--config\fP \fIFILENAME\fP
Read settings from the specified configuration file, in addition to
the default config files.
Configuration changes are saved to the last file thus specified and not
read-only at the time of loading.
.TP
\fB-C\fP, \fB--loadconfig\fP \fIFILENAME\fP
Read settings from the specified configuration file, in addition to
the default config files.
The file is not taken into account for saving configuration changes.
This is useful to mix-in partial configuration variants, particularly
colour schemes. However, \fB-o ThemeFile=\fIFILENAME\fP may be preferable.
.TP
\fB--dir\fP \fIdirectory\fP
Change initial directory to start in. This is especially useful for
invocation of mintty from a Windows context menu via registry entry.
.TP
\fB-e\fP, \fB--exec\fP \fIPROGRAM\fP [\fIARG\fP ...]
Execute the specified program in the terminal session and pass on any additional
arguments.
This option is present for compatibility with other terminal emulators only.
It can be omitted, in which case the first non-option argument, if any,
is taken as the name of the program to execute.
.TP
\fB-h\fP, \fB--hold\fP \fBnever\fP|\fBstart\fP|\fBerror\fP|\fBalways\fP
Determine whether to keep the terminal window open when the command has
finished and no more processes are connected to the terminal.
The argument can be abbreviated to a single letter.
By default, the window is closed immediately, except if the child process has
exited with status 255, which is used to indicate failure to execute the shell
command. (Exit status 255 is also used by \fBssh\fP to indicate connection
errors.)
Alternatively, the window can be set to never stay open, to always stay open,
or to stay open only if the child process terminates with an error, i.e. with
a non-zero exit status or due to a signal indicating a runtime error.
.TP
\fB-i\fP, \fB--icon\fP \fIFILE\fP[\fB,\fIINDEX\fR]
Load the window icon from an executable, DLL, or icon file. The optional
comma-separated index can be used to select a particular icon in a file with
multiple icons.
\fINote:\fP About interaction problems of icon, shortcut, and the Windows taskbar:
In a Windows desktop shortcut, to achieve consistent icon behaviour,
the same icon should be specified in the shortcut properties (Change Icon...)
and the mintty command line (Target:),
or (beginning 2.2.3) no icon should be specified on the command line as
mintty will then take the icon from the invoking shortcut,
also resolving a leading Windows environment variable (like %SystemRoot%).
.TP
\fB-l\fP, \fB--log\fP \fIFILE\fP|\fB-\fP
Copy all output into the specified log file, or standard output if a dash is
given instead of a file name.
If FILE contains \fB%d\fP it will be substituted with the process ID.
See description of equivalent option "Log file" (Log=) below
for further formatting options and hints.
Note that logging can be toggled from the extended context menu.
.TP
\fB--logfile\fP \fIFILE\fP|\fB-\fP
Like \fB--log\fP but with logging initially disabled, so just
specifying a potential log file name in case logging is enabled from
the extended context menu.
(Equivalent to combining \fB--log\fP with \fB-o Logging=no\fP.)
.TP
\fB-o\fP, \fB--option\fP \fINAME\fP=\fIVALUE\fP
Override the named config file option with the given value, e.g.
\fC-o ScrollbackLines=1000\fP.
.TP
\fB-p\fP, \fB--position\fP \fIX\fB,\fIY\fR
Open the window with its top left corner at the specified coordinates.
Instead of coordinates, "centre" or "center" can be specified to place
the window in the screen centre, and "right" or "bottom" can be specified
to align the right or bottom window border with the right or bottom
screen border (together with another option -p to specify an offset).
Option value "@N" where N is a number places the window on monitor N.
Multiple -p options can be combined; coordinates have a different meaning
depending on other options:
.br
\(en With "left", "top", or "@N", related coordinates are relative to the monitor.
.br
\(en With "right" or "bottom", related coordinates adjust the right or bottom
window border relative to the monitor.
.br
\(en Otherwise, coordinates are absolute and address the common multi-monitor
address space as provided by Windows.
\fINote:\fP For another option to select the monitor for a new mintty window,
see the description of Alt+F2.
.TP
\fB-s\fP, \fB--size\fP \fICOLS\fB,\fIROWS\fR
Set the default size of the window in character columns and rows.
(The xterm-like syntax \fICOLS\fBx\fIROWS\fR is accepted too.)
Instead of coordinates, "maxwidth" or "maxheight" can be specified;
this can be combined with another parameter \fB-s\fP for the other dimension.
The dimension for which "max" is applied is ignored in further \fB-s\fP or
\fB-p\fP parameters.
For example, \fBmintty -s maxwidth -p 0,0 -s 0,10\fP will start a window
at full screen width, positioned at the top of the screen, with 10 lines.
.TP
\fB--nobidi\fP, \fB--nortl\fP
Disable bidi display (right-to-left support).
.TP
\fB-t\fP, \fB--title\fP \fITITLE\fP
Use \fITITLE\fP as the initial window title.
By default, the title is set to the executed command.
.TP
\fB-T\fP, \fB--Title\fP \fITITLE\fP
Use \fITITLE\fP as the permanent window title.
The title is not changeable by control sequences.
This feature is only available on the command line.
.TP
\fB-B\fP, \fB--Border\fP \fBframe\fP|\fBvoid\fP
Suppress window title, display only a frame or no border.
This feature is only available on the command line.
.TP
\fB-u\fP, \fB--utmp\fP
Create a utmp entry.
.TP
\fB-w\fP, \fB--window\fP \fBnormal\fP|\fBmin\fP|\fBmax\fP|\fBfull\fP|\fBhide\fP
Set the initial window state: normal, minimised, maximised, full screen,
or hidden.
.TP
\fB--class\fP \fICLASS\fP
Use \fICLASS\fP as the window class name of the main window.
This allows scripting tools to distinguish different mintty instances.
The default is "mintty".
.TP
\fB-d\fP, \fB--nodaemon\fP
Do not apply "daemonizing".
By default, mintty tries to detach itself from the invoking terminal when
started from a Cygwin Console in order to avoid disabled signal reception,
and when cloning the window (Alt+F2) in order to avoid a remaining zombie process.
.TP
\fB-D\fP, \fB--daemon\fP
Enforce "daemonizing".
By default, mintty tries to detach itself from the invoking terminal only
as described above. With this option, it tries to detach always.
This makes a difference if a Windows "Shortcut key" is configured in a
Windows desktop shortcut for starting mintty. Without daemonizing, the
shortcut key will focus an already running instance of mintty, with
daemonizing it always starts a new instance.
.TP
\fB-R\fP, \fB--Report\fP \fIinfo/mode\fP
Report requested information.
With values "s" or "o", mintty reports the position and size of the window
when it exits. This can be used to manage last window positions and reopen
mintty windows accordingly.
Reporting mode is "s" or "o" to choose short or long option syntax for the
restored (i.e. neither maximised nor minimised) geometry;
min/max/fullscreen information is added.
With value "m", mintty reports the system's monitor configuration
(listing all connected monitors and their geometry and position in
Windows' virtual monitor coordinate system), and exits.
.TP
\fB--store-taskbar-properties\fP
Enable persistent storage of Windows taskbar properties together with
options AppName and AppLaunchCmd.
.TP
\fB--nopin\fP
Prevent pinning of the mintty window to the Windows taskbar.
.TP
\fB--wsl\fP
Adjust to WSL (the Windows Subsystem for Linux, or Bash/Ubuntu on Windows):
.br
\(en When dragging a Windows file or folder into mintty, it will be pasted
using the Linux path name.
.br
\(en When Ctrl+clicking a file name, it will be interpreted in the Linux
namespace and converted before opening in Windows.
.TP
\fB-H\fP, \fB--help\fP
Display a brief help message and exit.
.TP
\fB-V\fP, \fB--version\fP
Print version information and exit.
.SH USAGE
Mintty tries to adhere to both Windows and Unix usage conventions.
Where they conflict, an option is usually provided.
This section primarily describes the default configuration;
see the \fBCONFIGURATION\fP section on how it can be customised.
.SS Menus
The context menu can be opened by right-clicking the mouse (with Shift
in case right-click has been redefined or redirected to the application) or by
pressing the \fBMenu\fP key that is normally located next to the right Ctrl key.
If invoked while the Ctrl key is held down, an extended context menu will
be opened, with some additional entries.
Mintty also adds a couple of items to the window menu, which can be accessed
by clicking on the program icon or pressing \fBAlt+Space\fP.
Both menus have an entry that leads to the options dialog for changing mintty's
configuration.
.SS Copy & paste
Screen contents can be selected by holding down the left mouse button and
dragging the mouse. If Alt is held down before the left mouse button, a
rectangular block instead of whole lines will be selected.
The selection can be extended by holding down \fBShift\fP while left-clicking.
Double-clicking or triple-clicking selects a whole word or line, whereby word
selection includes special characters that commonly appear in file names and
URLs.
By default, selected text is automatically copied to the clipboard.
This can be disabled on the \fBMouse\fP page of the options dialog.
Selected text can also be copied manually using either the \fBCopy\fP menu
command, the \fBCtrl+Ins\fP or \fBCtrl+Shift+C\fP keyboard shortcuts
(\fBCtrl+C\fP with option CtrlExchangeShift=yes),
or the middle mouse button combined with \fBShift\fP.
The selected region is copied as "rich text" as well as normal text,
which means it can be pasted with colours and formatting into applications
that support it, e.g. word processors ("true colour" attributes are not supported).
The window title can be copied using the \fBCopy Title\fP command in the window
menu.
The clipboard contents can be pasted using either the \fBPaste\fP menu command,
the \fBShift+Ins\fP or \fBCtrl+Shift+V\fP keyboard shortcuts
(\fBCtrl+V\fP with option CtrlExchangeShift=yes),
or the middle mouse button.
Not only text but also files and directories can be pasted,
whereby the latter are inserted as Cygwin file names.
Shell quoting is added to file names that contain spaces or special characters.
.SS Drag & drop
Text, files and directories can be dropped into the mintty window.
They are inserted in the same way as if they were pasted from the clipboard.
.SS Opening files, directories and URLs
Files, directories, URLs and web addresses beginning with "www." can be
opened either by holding \fBCtrl\fP while left-clicking on them (or
double-clicking, if and as enabled by option OpeningClicks), or by
selecting them and choosing the \fBOpen\fP command from the context menu.
Please note that a relative file or directory path is interpreted as relative
to the current working directory of the terminal foreground process if that
can be determined.
.SS Font zoom
The font size can be increased or decreased using the keyboard shortcuts
\fBCtrl+(keypad-)plus\fP and \fBCtrl+(keypad-)minus\fP,
or by holding \fBCtrl\fP while rolling the mousewheel.
\fBCtrl+zero\fP or \fBCtrl+middle-mouse click\fP returns the font size
to the default.
.br
\fIShift-coupled window-with-font zooming:\fP
If Shift is also held while zooming, the window will be resized to scale
together with the font, keeping the terminal character size if possible.
This is not applied to the shifted numeric keypad "0" (which has other
meaning) and to the shifted normal (non-keypad) "-" and "+" keys
(because the shifted key could have a valid mapping, e.g. Ctrl+_, or the
"+" key could be shifted itself already).
.br
Zooming by keyboard or mouse can be disabled, respectively, with options
ZoomShortcuts=no or ZoomMouse=no.
.SS Drag resize
The usual windows function to drag on the window border resizes the terminal.
.br
\fIShift-coupled font-with-window zooming:\fP
If Shift is also held while resizing, the font will be scaled along with
the resizing, unless disabled with ZoomFontWithWindow=false
(which would help to avoid interference with certain shifted hotkeys configured
to resize the window).
.br
Note that due to the different height/width factors, coupled font zooming
is not a precise operation.
.SS DPI change
When DPI setting changes (by reconfiguration of display properties
"what's on your screen ... smaller/medium/larger" or moving the mintty window
between monitors with different DPI settings), mintty adapts its screen
size to avoid Windows blurred auto-adaptation. If Shift is also held during
the change, the font will be scaled too, roughly maintaining the screen
dimensions.
.SS Full screen
Full screen mode can be toggled using either the \fBFull Screen\fP command in
the menu or either of the \fBAlt+Enter\fP and \fBAlt+F11\fP keyboard shortcuts,
or the generic window title functions.
.SS Default size
If the window has been resized, it can be returned to the default size set in
the Window pane of the options using the \fBDefault size\fP command in the
menu or the \fBAlt+F10\fP shortcut.
\fBShift+Alt+F10\fP also restores the font size to its default.
.SS Reset
Sometimes a faulty application or printing a binary file will leave the
terminal in an unusable state. In that case, resetting the terminal's state
via the \fBReset\fP command in the menu or the \fBAlt+F8\fP keyboard shortcut
may help.
.SS Scrolling
Mintty has a scrollback buffer that can hold up to 10000 lines in the default
configuration.
It can be accessed using the scrollbar, the mouse wheel, or the keyboard.
Hold the \fBShift\fP key while pressing the \fBUp\fP and \fBDown\fP arrow keys
to scroll line-by-line or the \fBPageUp\fP and \fBPageDown\fP keys to scroll
page-by-page.
.SS Searching in the text and scrollback buffer
Alt-F3 opens a search bar with an input field for a search string. Matches are
highlighted in the scrollback buffer. Enter/Shift+Enter find the next/previous
position of the match and scrolls the scrollback buffer accordingly.
The appearance of the search bar and the matching highlight colours can be
customized.
.SS Flip screen
Applications such as editors and file viewers normally use a terminal feature
called the alternate screen, which is a second screen buffer without scrollback.
When they exit, they switch back to the primary screen to restore the command
line as it was before invoking the application.
The \fBFlip Screen\fP menu command and \fBAlt+F12\fP shortcut allow looking
at the primary screen while the alternate screen is active, and vice versa.
For example, this allows to refer to past commands while editing a file.
.SS Switching session
The \fBCtrl+Tab\fP and \fBCtrl+Shift+Tab\fP shortcuts can be used to switch
between mintty windows. Minimised windows are skipped.
.SS Closing a session
Clicking the window's close button, pressing \fBAlt+F4\fP, or choosing
\fBClose\fP from the window menu sends a \fISIGHUP\fP signal to the process
running in mintty, which normally causes it to exit.
That signal can be ignored, though, in which case the program might have to be
forced to terminate by sending a \fISIGKILL\fP signal instead.
This can be done by holding down \fBShift\fP when using the close button,
shortcut or menu item.
.SS Mouse tracking
When an application activates mouse tracking, mouse events are sent to the
application rather than being treated as window events.
This is indicated by the mouse pointer changing from an \fBI\fP shape to an
arrow.
Holding down \fBShift\fP overrides mouse tracking mode and sends mouse
events to the window instead, so that e.g. text can be selected and the
context menu can be accessed.
.SS Alt codes
The Windows Alt+Numpad method for entering character codes is supported,
whereby the Alt key has to be held while entering the character code.
Only the first key has to be on the numpad; subsequent digits can be entered
both on the numpad or the main part of the keyboard.
If the first key is the \fB'+'\fP on the numpad, the code is interpreted as
hexadecimal, whereby digits A through F can be entered using the letter keys.
If the first key is a zero, the code is interpreted as octal.
If the first key is any other digit from 1 to 9, the code is interpreted as
decimal.
For UTF-8 and other Unicode encodings such as GB18030, the entered code is
interpreted as a Unicode codepoint and encoded accordingly before it is sent.
For other encodings, the entered code is sent as is.
If it doesn't fit into one byte, it is sent as multiple bytes, with
the the most significant non-zero byte first.

Multi-monitor selection support: Alt+F2 will only spawn a new window
after F2 has been released. While F2 is being held, the target monitor
can be selected with a sequence of numeric keypad keys:
.br
\(en cursor-up/down/left/right (8/2/4/6) navigate the target focus to the
respective neighbour in the monitor grid;
.br
\(en the diagonal keys (7/9/1/3) combine two directions respectively;
.br
\(en the central key (5) sets the target focus to the Windows "primary" monitor;
.br
\(en the Ins key (0) or Del resets the focus to the current monitor.
.br
These navigation controls can be applied repeatedly to select a monitor further away.
Note that a heuristic algorithm is used, based on the size of the smallest
monitor attached to the system, so the target may not always be selected
as expected if multiple monitors of different size are available or
monitors are not arranged in a regular grid.

Ctrl+Shift+T cycles through transparency levels in steps, whenever
Ctrl+Shift+T is released. Alternatively, while Ctrl+Shift+T is held down,
the navigation keys on the numeric keypad can be used for further fine-tuning:
.br
Up/Dn to increase/decrease, PgUp/PgDn for steps, Del/Ins for no/max transparency,
End for highest preconfigured transparency, Home for previous value,
Clear ("5") for glass.
.br
If OpaqueWhenFocused is set, opaqueness is temporarily disabled to
provide visible feedback for the changes.
.SS Embedding graphics in terminal output
The new support of the SIXEL feature facilitates a range of applications
that integrate graphic images in the terminal, animated graphics, and even
video and interactive gaming applications.
An example of the benefit of this feature is the output of `gnuplot`
with the command
.br
GNUTERM=sixel gnuplot -e "splot [x=-3:3] [y=-3:3] sin(x) * cos(y)"
.SS Diagnostic support
.TP
\fBScreen logging\fP
A couple of options are available to enable logging initially
(\fBLog=...\fP or \fB-l ...\fP on the command line), or to specify
a log file name for later logging (\fBLog=...\fP combined with \fBLogging=no\fP,
or \fB--logfile ...\fP on the command line).
In either case, logging can be toggled from the extended context menu.
.TP
\fBCharacter information display\fP
Diagnostic display of current character information can be toggled
from the extended context menu.
.br
\fIUnicode character codes\fP at the current cursor position will then be display in the window title bar. (Note that mintty may precompose a combining character sequence into a combined character which is then displayed.)
.br
\fIUnicode character names\fP will be included in the display if the \fBunicode-ucd\fP package is installed in \fI/usr/share\fP (or the file \fIcharnames.txt\fP generated by the mintty script \fIsrc/mknames\fP is installed in the mintty resource subfolder \fIinfo\fP).
.br
Note that the "normal" window title setting sequence
and the character information output simply overwrite each other.
.SH CONFIGURATION
Mintty has a graphical options dialog that can be reached via the context menu
or the window menu. It has the following action buttons:
.br
\(en \fBCancel\fP: discards changes.
.br
\(en \fBSave\fP: applies and saves changes and closes the dialog.
.br
\(en \fBApply\fP: applies changes to the current instance of mintty
but does not save them to the configuration file. So using \fBApply\fP
then \fBCancel\fP, local changes can be applied (and tested) without
affecting further instances of mintty.
In configuration files, settings are stored as \fINAME\fP=\fIVALUE\fP pairs,
with one per line. By default, they are read from any file of
\fI/etc/minttyrc\fP, \fI$APPDATA/mintty/config\fP,
\fI~/.config/mintty/config\fP, \fI~/.minttyrc\fP, in this order.
Additional configuration files can be specified using the
\fB-c\fP/\fB--config\fP or \fB-C\fP/\fB--loadconfig\fP command line options.
These are read in order after the default config files,
with settings in later files overriding those in earlier ones.
Configuration changes are saved to the last writable file
read by default or specified with \fB-c\fP/\fB--config\fP,
or \fI~/.minttyrc\fP if none is given.
Individual settings can also be specified on the command line using the
\fB-o\fP/\fB--option\fP.
\fINote:\fP Many string values in the config files, especially those
referring to file names or Windows items, are \fBUnicode-enabled\fP,
meaning they are expected to be UTF-8-encoded in the configuration
file independently of the encoding the terminal runs in; as a fallback,
if the configuration value is not valid UTF-8, it is interpreted in
the system ANSI encoding.
(This does not apply to the same configuration settings when given on the
command-line.)
.br
Unicode-enabled settings: BellFile, ThemeFile, Title, ExitTitle, Icon, Log,
Language, Font, Printer, Answerback, SixelClipChars,
Class, AppID, AppName, AppLaunchCmd, DropCommands.
Be careful when running multiple instances of mintty. If options are saved
from different instances, or the config file is edited manually,
options can obviously be overwritten; if older mintty versions are run
(e.g. from cygwin and msys sharing the same home directory), options
may even get dropped from the configuration file; mintty versions since
261 preserve unknown options and comment lines.
Additional resource files are used for colour schemes (option ThemeFile,
subdirectory \fIthemes\fP), wave files (option BellFile, subdirectory \fIsounds\fP),
and localization translation files (option Language, subdirectory \fIlang\fP)
within the mintty resource directories \fI~/.mintty\fP, \fI~/.config/mintty\fP,
\fI$APPDATA/mintty\fP, \fI/usr/share/mintty\fP.
The following sections explain the settings on each pane of the options
dialog, followed by settings that do not appear in the dialog.
For each setting, its name in the config file is shown in parentheses,
along with its default value.
If there is only a name in parentheses, there is currently
no GUI configuration facility for that option
(see also Hidden settings below).
.SS Looks
Settings affecting mintty's appearance.
.TP
\fBColours\fP
Clicking on one of the buttons here opens the colour selection dialog.
.br
In the settings (config file or command-line options), colours are
represented as comma-separated RGB triples with decimal 8-bit values
ranging from 0 to 255. X-style hexadecimal colour specifications such
as #RRGGBB, rgb:RR/GG/BB or rgb:RRRR/GGGG/BBBB can be used as well.
Also X11 color names are supported.
.br
\(en \fBForeground\fP (ForegroundColour=191,191,191)
.br
\(en \fBBackground\fP (BackgroundColour=0,0,0)
.br
\(en \fBCursor\fP (CursorColour=191,191,191)
.br
\(en \fBUnderline, Strikeout, Overline\fP (UnderlineColour=-1)
\(en \fBTheme\fP (ThemeFile=):
The popup offers theme files as stored in a resource subdirectory
\fIthemes\fP for selection as a colour scheme.
The option can also be set to a filename (like D:/.../solarized-light.minttyrc).
The field can also be used as a drag-and-drop target for colour schemes
downloaded from the Color Scheme Configurator, or for theme files from the web
(note that the program \fBcurl\fP needs to be installed for the latter option).
See the Tips wiki page \fIhttps://github.com/mintty/mintty/wiki/Tips#using-colour-schemes-themes\fP
about this mechanism.
.TP
\fBTransparency\fP (Transparency=off)
Window transparency level, with the following choices:
.br
\(en \fBOff\fP
.br
\(en \fBLow\fP
.br
\(en \fBMedium\fP
.br
\(en \fBHigh\fP
.br
\(en \fBGlass\fP
The \fBGlass\fP option is only available on Vista and above with desktop
compositing enabled.
To make this reasonably usable, the glass colour needs to be set to be as dark
as possible in the Windows control panel: choose \fIPersonalize\fP from the
desktop context menu, click on \fIWindow Color\fP, turn the colour intensity up
to the maximum, show the colour mixer, and turn the brightness down to black.
Numeric transparency values ranging from 4 to 254 can be specified in config
files or on the command line. (Values below 4 are multiplied by 16, for
backward compatibility reasons.)
.TP
\fBOpaque when focused\fP (OpaqueWhenFocused=no)
Enable to make the window opaque when it is active (to avoid background
distractions when working in it).
.TP
\fBCursor\fP (CursorType=line)
The following cursor types are available:
.br
\(en \fBLine\fP
.br
\(en \fBBlock\fP
.br
\(en \fBUnderscore\fP
The line cursor is displayed with the width set in the Accessibility Options
control panel / Ease of Access Center, mouse panel or Optimize visual display.
.TP
\fBCursor blink\fP (CursorBlinks=yes)
If enabled, the cursor blinks at the rate set in the Keyboard control panel.
.SS Text
Settings controlling text display.
.TP
\fBFont selection\fP
Clicking on the \fBSelect\fP button opens a dialog where the font and its
properties can be chosen. Font styles other than \fBBold\fP are ignored.
In the config file, this corresponds to the following entries:
.br
\(en \fBFont\fP (Font=Lucida Console)
.br
\(en \fBFont style\fP (FontWeight=400, FontIsBold=no)
.br
\(en \fBSize\fP (FontHeight=9)
.br
The font selection dialog also offers an \fBApply\fP button for
convenient testing how the selected font looks. Its function is the same
as the \fBApply\fP button of the options dialog.
Further settings can be given in the config file:
.br
\(en \fBFont boldness\fP (FontWeight=400): This is an implicit value after
selecting a font in the font selection menu, or can be specified in the
config file or on the command line for font selection. Typical weights
are \fBNormal\fP/\fBRegular\fP (FontWeight=400) and \fBBold\fP (FontWeight=700
or FontIsBold=yes) but if a font family has a different scheme or more than
2 font weights, the weight value can be used for more specific selection.
If a font family has no bold weight but boldness was requested, mintty
does not adhere to this scheme but enforces bold font selection; however,
in this case the bold attribute may not be effective.
.br
\(en \fBFont sample text\fP (FontSample=):
This setting overrides the text for the "Sample" box in the Font chooser dialog.
.br
\(en \fBShow "hidden" fonts\fP (ShowHiddenFonts=no):
This hidden setting enables display of monospace fonts in the font selection
menu even if they are marked to Hide in the Windows Font settings (from the
Control Panel \(em Fonts folder).
.TP
\fBText lines\fP (UnderlineManual=false)
By setting this true, text attributes underline, doubly underline, strikeout and overline
are enforced to be drawn manually.
The default is to use Windows font variants for strikeout and for underline,
unless mintty detects that the underlined font would not display properly.
.TP
\fBShow bold as font\fP (BoldAsFont=no)
When this option is enabled, the ANSI bold (or 'intense') text attribute is
shown as a bold-style font. Where a bold variant of the selected font that
has the same width as the base font is available, that is used; otherwise, the
bolding is simulated by rendering the text twice with a one-pixel offset.
.TP
\fBShow bold as colour\fP (BoldAsColour=yes)
By default, text with the ANSI bold attribute set is displayed with a
different colour, usually with increased brightness. This can be disabled
here.
Note that when \fBBoldAsFont\fP is enabled, only bold text in one of the eight
ANSI colours has its colour changed, i.e. bold text without an explicitly
specified colour is shown with a bold font only. This matches \fBxterm\fP behaviour.
This option also controls how the 'half-bright' (or 'dim') text
attribute is displayed: if it is on, half-bright text is
shown with halved foreground colour brightness; otherwise, it is shown
by blending the foreground colour with the background colour.
.TP
\fBAllow blinking\fP (AllowBlinking=no)
When text blinking is disabled, as it is by default, the blink attribute is
displayed as a bold background colour instead.
.TP
\fBFont smoothing\fP (FontSmoothing=default)
Select the amount of font smoothing from the following choices:
.br
\(en \fBDefault\fP: Use Windows setting.
.br
\(en \fBNone\fP: With all the jaggies.
.br
\(en \fBPartial\fP: Greyscale anti-aliasing.
.br
\(en \fBFull\fP: Subpixel anti-aliasing ("ClearType").
.TP
\fBFont rendering\fP (FontRender=textout)
Select the rendering system used for text display:
.br
\(en \fBtextout\fP: Use the Windows ExtTextOut API.
.br
\(en \fBuniscribe\fP: Use the Windows Uniscribe API.
This may become the default in a future version.
.TP
\fBLocale\fP (Locale=)
The locale setting consists of a lowercase two-letter or three-letter language
code followed by a two-letter country code, for instance \fBen_US\fP or
\fBzh_CN\fP. The Windows default system and user locales are shown in the
drop-down list for this setting. Alternatively, the language-neutral "C"
locale can be selected.
If no locale is set here, which is the default, mintty uses the locale and
character set specified via the environment variables \fILC_ALL\fP,
\fILC_CTYPE\fP or \fILANG\fP.
If the locale option is set, however, it will override any environment
variable setting: \fILC_ALL\fP and the \fILC_*\fP variables for specific
locale categories are cleared, while \fILANG\fP is set according to the
selected locale and character set.
\fINote:\fP This means, while not strictly necessary, that also locale variables
unrelated to the terminal character set (e.g. LC_MESSAGES) are cleared
to avoid confusion.
.TP
\fBCharacter set\fP (Charset=)
The character set to be used for encoding input and decoding output.
If no locale is set, this setting is ignored.
\fINote:\fP
While changing the character set takes effect immediately for text input and
ouput, it does not affect the processes already running in mintty.
This is because the environment variables of a running process cannot be
changed from outside that process.
Therefore mintty should be restarted for a character set change to take full
effect, or the locale environment of the shell should be changed accordingly.
\fINote:\fP
The locale and character set can also be changed with an escape sequence,
see the Control Sequences wiki page \fIhttps://github.com/mintty/mintty/wiki/CtrlSeqs#locale\fP.
That setting takes precedence; changes from the Options menu will silently
have no effect unless an escape sequence with empty locale is sent
to the terminal to restore to "default".
.SS Keys
Settings controlling keyboard behaviour.
.TP
\fBBackarrow sends ^H\fP (BackspaceSendsBS=no)
By default, mintty sends \fB^?\fP (ASCII DEL) as the keycode for the backspace key.
If this option is enabled, \fB^H\fP is sent instead.
This also changes the \fBCtrl+Backspace\fP code from \fB^_\fP to \fB^?\fP.
(Corresponds to the xterm resource \fBbackarrowKey\fP.)
.TP
\fBDelete sends DEL\fP(DeleteSendsDEL=no)
By default, mintty sends VT100 Remove as the keycode for the keypad Del key.
If this option is enabled, \fB^?\fP (ASCII DEL) is sent instead.
(Corresponds to the xterm resource \fBdeleteIsDEL\fP.)
.TP
\fBCtrl+LeftAlt is AltGr\fP (CtrlAltIsAltGr=no)
The AltGr key on non-US Windows systems is a strange beast: pressing it is
synonymous with pressing the left Ctrl key and the right Alt key at the
same time, and Windows programs usually treat any Ctrl+Alt combination as
AltGr.
Some programs, however, chief among them Microsoft's very own Office, do not
treat Ctrl+LeftAlt as AltGr, so that Ctrl+LeftAlt combinations can be used in
command shortcuts even when a key has an AltGr character binding.
By default, mintty follows Office's approach, because a number of terminal
programs make use of Ctrl+Alt shortcuts.
The "standard" Windows behaviour can be restored by ticking the checkbox here.
The setting makes no difference for keys without AltGr key bindings
(e.g. any key on the standard US layout).

\fBCopy and Paste shortcuts\fP (ClipShortcuts=yes)
Checkbox for enabling the clipboard shortcuts \fBCtrl+Ins\fP for copying and
\fBShift+Ins\fP for pasting.
.TP
\fBMenu and Full Screen shortcuts\fP (WindowShortcuts=yes)
Checkbox for enabling the \fBAlt+Space\fP and \fBAlt+Enter\fP shortcuts for
showing the window menu and toggling full screen mode.
.TP
\fBSwitch window shortcuts\fP (SwitchShortcuts=yes)
Checkbox for enabling the \fBCtrl+Tab\fP and \fBCtrl+Shift+Tab\fP shortcuts
for switching between mintty windows.
.TP
\fBZoom shortcuts\fP (ZoomShortcuts=yes)
Checkbox for enabling the font zooming shortcuts \fBCtrl+plus/minus/zero\fP.
.TP
\fBAlt+Fn shortcuts\fP (AltFnShortcuts=yes)
Checkbox for enabling the use of combinations of Alt and functions keys as
shortcuts, for example \fBAlt+F4\fP for closing the window or \fBAlt+F11\fP
fortoggling full screen mode. Disable to have \fBAlt+Fn\fP combinations
sent to applications instead.
.TP
\fBCtrl+Shift+letter shortcuts\fP (CtrlShiftShortcuts=no)
Checkbox for enabling alternative clipboard and window command shortcuts
using \fBCtrl+Shift+letter\fP combinations such as \fBCtrl+Shift+V\fP for
paste or \fBCtrl+Shift+N\fP for starting a new session.
These can replace the \fBCtrl/Shift+Ins\fP and \fBAlt+Fn\fP shortcuts, whereby
they show up in menus only if the corresponding default shortcuts are disabled.
See the shortcuts section above for the list of shortcuts controlled by this
option. When it is disabled, Ctrl+Shift+letter combinations are sent to
applications as C1 control characters instead.
.TP
\fBCompose key selection\fP (ComposeKey=off)
The modifier key selected here will have the function of a \fICompose key\fP.
Pressing and releasing the key, following by a sequence of composing keys,
will enter a composition of them, according to X11 compose key data.

\fBCopy on select\fP (CopyOnSelect=yes)
If enabled, the region selected with the mouse is copied to the clipboard as
soon as the mouse button is released, thus emulating X Window behaviour.
