Hi, how do I configure the 'looking glass' or 'magnifier' zoom so that it responds to <SOME_KEY> + mouse wheel forward/backward? Obviously, this should be the default setting, but I guess the people who came up with this feature don't have any 'accessibility' problems themselves and never use these tools...because why would anyone want to use the keyboard to do this?!

Hmm...seems that none of the desktop effects support mouse bindings...is that right?

Agh, nevermind. I'll use xbindkeys or something...
