get-key-code in key-event%
Gets the virtual key code for the key event. The virtual key code is either a character or a special key symbol, one of the following:
The special key symbols attempt to capture useful keys that have no standard ASCII representation. A few keys have standard representations that are not obvious:
#\space-- the space bar#\return-- the Enter or Return key (on all platforms), but not necessarily the Enter key near the numpad (which is reported as'numpad-enterif the platform distinguishes the two Enter keys)#\tab-- the tab key#\backspace-- the backspace key#\rubout-- the delete key
If a suitable special key symbol or ASCII representation is not
available, #\nul (the null character) is
reported.
Under X, a 'wheel-up or 'wheel-down event may be sent
to a window other than the one with the keyboard focus, because X
generates wheel events based on the location of the mouse pointer.
