Difference between separate keystrokes and continuous swtching

[klayman]

I've just tried the released version with #5 fixed and its behavior differs from that of the sort-by-access branch.

Say, there are three windows: A1, A2 and A3 and a keystroke alt+A to switch between them. In the prototype pressing A key while holding alt cycled in order A3->A2->A1->A3..., and separate keystrokes alt+A switched between A3 and A2 - I think this should be the expected behavior. In the latest code, though, separate keystrokes cycle through all windows A3->A2->A1->A3... as well, making it hard to reach the two last used.
