Actually, redefining a key binding is easy by providing a ney key
extension for the extension point org.eclipse.ui.bindings. Now I have
the following problem: Sometimes a pre-defined key-binding is just ugly,
e.g. I consider the pre-defined key-binding for the CollapseAll handler
as "ugly", "M1+M2+NUMPAD_DIVIDE" is just a mess. In this case it would
be ideal for us, if this Handler would not provide *any* key-binding at
all. But according to the extension point definition
org.eclipse.ui.bindings#key the value is required. Does there exist an
officially supported mechanism to remove a key-binding or replacing it
my something that corresponds to 'no-binding-at-all' magic?
Thanks & Greetings from Bremen,

OK, that worked, thanks!

I have problems to follow you here, could you elaborate, please?
1) Is the "delete marker" the above mentioned keybinding registration
that omits the commandId?
2) I don't understand, in which sense "SYSTEM" and "users" are entering
the game here.
Do you want to describe that by doing above effective removal of the
key-binding "M1+M2+NUMPAD_DIVIDE" I can never reassign this binding to
another command?

OK, I understand - even though I never have looked at it with such roles
in my mind.

Thanks for your thorough explanation, Paul - it was very helpful.
