 <para>When specifying the <link linkend="texttext">text</link> attribute of the <link linkend="Text">Text</link> control or any tooltip attribute, you can insert escape sequences which will be expanded dynamically. An escape sequence always starts with the '$' character, followed by one or more predefined letters. Here is the list of accepted escape sequences:</para>
