Comment 38 for bug 161960

Not every Ubuntu user has a mouse with scroll wheel, so let's forget implementing it. Sorry, Teej, but this argumentation is just silly.

I believe this key can be set in addition to Alt-F1 (so Mac users can be happy) and be used *only when released*, so all super+<key> shortcuts will work. This way there would be no harm to anybody and a gain for a large group of users.

That's for clarification. Thank you :)
