Cycle between the last two windows (similar to CMD+TAB) I generally have two screens but I'm stuck with just a laptop for a while.

Is there a way to cycle between the last two apps you're using? CommandTab would cycle between all open apps. I'd like just between the last two.

A workaround I have is to maximize the screen of the two applications I'm using, and Control→ or Control← to cycle between the Desktops but is there something easier that happens in the same Desktop?
Cmd ⌘   Tab ⇥    already does that, so long as you let go in between &amp; let the 2nd app come to the front. 

That then makes your previous 1st app the 2nd - therefore 1st to switch to when you  Cmd ⌘   Tab ⇥
