Binding two actions to a single key

[CorianderCastor]

I would like the ability to bind flyup and jump to the same key. Is it possible? I don't know how to call actions from the console. So the classic alias approach doesn't seem to work. This isn't an issue until Hexen support or a mod that requires flying and jumping.

Vanilla is all capable for that, so I guess this deserves attention...
