keymap%

A keymap% object is used by editor<%> objects to map keyboard and mouse sequences to arbitrary functions in an extensible way. Keymaps can be used without editors, as well. A keymap% object contains

• a mapping from function names to event-handling procedures; and
• a mapping from key and mouse sequences to function names .

A handler procedure in a keymap is invoked with a key-event% object or a mouse-event% object. It is also given another value that depends on the context in which the keymap is used (or, more specifically, the arguments to handle-key-event or handle-mouse-event). For keymaps associated with editor<%> objects, the extra parameter is generally the editor<%> object that received the keyboard or mouse event.
