Changing key bindings in Mac OS X

[Scott Tringali]

Hi,

You probably want to fix this for all text widgets rather than just the 
main editor widget.

The way to do this is with virtual bindings.  Ideally, your X server 
would do this for you but nobody cares about Motif anymore so... get 
ready to hack a bit.

This guy mapped to 'F9' but you can see the pattern.  In your case, you 
probably want to use "Shift Ctrl<Key>-" for osfInsert.

See "man VirtualBindings" for more info.
