[Not addressed to anyone in particular:]

In the long run, I think it could be really useful with multikey shortcuts... given the number of bundles and the number of commands one wants available at all times. It would be easier to set up some sort of hierachy that way, and easier to avoid clashes.  I'm not saying this should be used all the time, but then the primary items could carry normal hotkeys, and all the not so often used ones could have the secondaries.

This is not a feature suggestions as such; I know it's been up and is somewhere on a list of things to consider. Just making a point, seeing how every now and then the problem of 'what hotkey should we use' comes up.
