\func{void}{OnKeyDown}{\param{wxKeyEvent\&}{ event}}
Called when the user has pressed a key, before it is translated into an ASCII value using other
modifier keys that might be pressed at the same time.
\wxheading{Parameters}
\docparam{event}{Object containing keypress information. See \helpref{wxKeyEvent}{wxkeyevent} for
details about this class.}
\wxheading{Remarks}
This member function is called in response to a key down event. To intercept this event,
use the EVT\_KEY\_DOWN macro in an event table definition. Your {\bf OnKeyDown} handler may call this
default function to achieve default keypress functionality.
