+/** \class Fl_Shortcut_Button
+ A button that allows the user to type a key combination to create shortcuts.
+ After clicked once, the button catches the following keyboard events and
+ records the pressed keys and all modifiers. It draws a text representation of
+ the shortcut.
+
+ The backspace key deletes the current shortcut. A second click on the button
+ or moving focus makes the last shortcut permanent.
+
+ The Shortcut button calls the user callback after every change if
+ FL_WHEN_CHANGED is set, and when the button is no longer recording
+ shortcuts if FL_WHEN_RELEASE is set.
