I once went crazy with assigning hotkeys to do various things with my computer. As a result, I lost track which program owns which hotkey. Some of these hotkeys seem to do nothing at all. For instance, when I press CTRL-SPACE, nothing happens, even if I do this in a program which should do something after a CTRL-SPACE.

So, is it possible to write a program that tells you which program registered a combination of keys as a hotkey? As a bonus, it could also have the feature to force the hotkey to become unassigned. It would be nice if it worked with hotkeys involving the WINDOWS key, too.

Or does something like this already exist? I couldn't find it...

Thanks,
