h1(#wxkeycodes). Key Codes

KeyCodes are a set of an integer constants constants pertinent to key
presses.  These values may be returned, for example, by methods in
"KeyEvent":keyevent.html. The possible values are the ASCII character
codes, plus those detailed below. In ruby, the ASCII character code can
be obtained by prefixing a "?" to the character:

 a_key = ?a # 65

To get unicode characters from a KeyEvent, use
"KeyEvent#get_unicode_key":keyevent.html#KeyEvent_getunicodekey.

To identify keys, such as "backspace" or "enter", that don't have a
character representation, use the constants listed below:
