In Linux, are there any plug-ins to let me do `<Win>`+`<Num>` style app switching (like Windows 7's superbar)?

Question

Using Windows 7's superbar, I can select/launch the 2nd application group by <Win>+<2>. We have DockbarX in GNOME, which is nice (grouping the windows like Windows 7), but it doesn't enable the <Win>+<2> style keybaord shortcuts.

Any suggestions?

This is not restricted to making Linux like Windows. But I just find the <Win>+<2> style shortcut very useful. Are there similar ways in Linux to quickly switch between specific apps without pressing <Alt>+<Tab> many many times?

Answer 1

I'm planning on adding something like that to the next version of DockbarX. It will probably be super+s (or something similar) and then the number instead of super+number straight away, because that is simpler to implement.

Oh, and Unity is also implementing this (super+number).
