Sadly I already remap caps-lock to ctrl. Don't worry though, this SB2 is so nice I'm no longer feeling any pain. Literally my only complaint about it so far is that the headphone jack is in the wrong place (it's on the edge of the screen in the upper right, which is sort of an odd place for a wire to be coming out. It should be on the lower edge either left or right.)

You can do both. Have it act as ctrl when held (for shortcuts) and as Esc when released on its own:

I presume there is similar software for windows.

What about your ctrl key? You could remap that to esc.

It's a pain to reach. And now that I have an escape key, no need.
