Looking for a specific shortcut program...

[allucid]

I am having trouble finding this (maybe it doesn't exist)...

Is there a program that is acessed like the alt+tab window in Windowz (for lack of a better example) that can be used to launch programs.

Here's how it would work:
-You press (for example) Ctrl+Tab and it would bring up a bar in the middle of the screen with user configured icons in it.
-You keep Ctrl held down but each time you hit Tab it selects the next icon on the bar.
-When you release Ctrl and Tab it launches the program associated with the icon you had selected.
