add-key-function

Names a new function to handle keyboard events. If there was already a function mapped to this name, it will be overridden. The namespaces for key and mouse event handlers are separate.

• (send a-wx:keymap add-key-function name func) -> void
      name : string
      func : a procedure of two arguments -- a wx:object% object and

  a wx:key-event% object -- that returns a boolean

  If func returns #f, the event is handled by the default handler.
