#2 Hotkeys for browsing

[GodzillaXP]

Support for hotkeys would be great.

I already can navigate throu the trees by using the arrow-keys.
It would be great to start "get" or "walk" with a simple hotkey instead of using the mouse.
Like "Alt-W" for walk for example.
Alt-G for Get
Alt-N for Get Next
Alt-S for Set..
and so on.
