For the record, this works because wxSTC is a generic control and so it 
is  driven all from wx events.  If you had tried doing the same with a 
native widget such as a wxTextCtrl it would not work because an 
unhandled key event sent this way does not get converted to a native 
platform event and forwarded on to the native widget as if the user had 
pressed the key.
