Capturing *all* key events [message #447574]

Up against a wall and was wondering if anyone has any ideas...

I'm writing a view for which I'd like to be able to capture *all* key
events, even those for which keyboard shortcuts have been registered.
(It's a terminal view - I need to be able to get at all the control
characters, function keys, etc.) Is there any way to get first crack at
key events before accelerators are processed?

I've have a little luck adding a KeyDown filter on the Display immediately
after creating it - that captures some but not all events. I need 'em all!

You can't. By definition, accelerators are handled before key events and
are eaten if a match occurs. For this reason, Eclipse doesn't use real
operating system accelerators to implement key bindings.
