+Defines the action that Flex Launcher will take upon the launch of an application. Possible values: "Hide", "None", and "Blank"
 - Hide: Flex Launcher will hide its window while the application is running, and then show itself again after the application has closed. This avoids window focus conflicts between the launcher and the application, but will cause the desktop to be briefly visible when an application is launched
-- None: Flex Launcher will maintain its window, and the launched application will have to draw itself over Flex Launcher. The desktop will never be visible, but this mode could cause window focusing conflicts depending on your configuration
+- None: Flex Launcher will maintain its window, and the launched application will have to draw itself over Flex Launcher.

 ## Creating Menus
 At least one menu must be defined in the configuration file, and the title must match the ```DefaultMenu``` setting value. The title of the menu is the section name. Any title may be used that is not reserved for another section, such as "Settings", and "Gamepad". The entries of the menu are implemented as key=value pairs. The name of the key will be ignored by the program, and is therefore arbtrary. However, it is recommended to pick something intutitive such as Entry1, Entry2, Entry3, etc. The entry information is contained in the value.

+## Hotkeys
+Flex Launch supports configurable hotkeys, which executes a command when a specified key is pressed. Each hotkey consists of a key=value pair, where the key is an arbitrary name, and the value contains the SDL keycode of the hotkey and the command to run when it is pressed, delimited by a semicolon:
+```
+Hotkey=keycode;command
+```
+The keycode is a HEX value *without* any 0x or # prefix. There are two ways to find a keycode for a given key. The first is to use the [lookup table provided by SDL](https://wiki.libsdl.org/SDLKeycodeLookup). The name of each key is in the right column of the table, and the corresponding HEX keycode is in the center column. The second is to [run Flex Launcher in debug mode](../../README.md#debugging), press the key, then check the log. For each keystroke, the name of the key will be printed and the HEX value will be in parenthesis next to it.
+
+Any key can be set as a hotkey, except keys that are reserved for the default controls: the left/right arrow keys, enter/return, and backspace. Hotkeys may be used to "speed dial" your favorite applications, or to add controls via [special commands](#special-commands). As an example configuration below, the first hotkey is mapped to F1 and will launch Kodi when it is pressed, and the second hotkey is mapped to F12 and will cause Flex Launcher to quit when it is pressed:
+```
+[Hotkeys]
+Hotkey1=4000003A;"C:\Program Shortcuts\kodi.lnk"
+Hotkey2=40000045;:quit
+```
+
 ## Gamepad Controls
 Flex Launcher has built-in support for gamepad controls through SDL. All settings for gamepads will be in a section titled ```Gamepad```. Within the section, there are key=value pairs which define the gamepad settings and the commands to be run when a button or axis is pressed.
