Define additional shortkey with the same effect like RETURN in Safari.app I'm working with MacOS X 10.6.

I'd like to define a keyboard shortcut Ctrl-m, which does the same thing like RETURN does, without deactivating RETURN.

How can I do that in MacOS X 10.6. In the keyboard control panel, I can only assign menu commands to shortcuts, but RETURN is not a menu command, but a key that does different things in different locations.

How can I do that?



Remark:


I would prefer a built-in or at least free solution. I'm using Quicksilver already, so if it would be able to define such a key/trigger, that would also be helpful.
If you wonder, why I want to do it, you'll find the explanation here: https://emacs.stackexchange.com/questions/3544/is-there-a-more-convenient-key-binding-for-return
You could do it using Keyboard Maestro.
