anker keyboard escape key My imac bluetooth keyboard had some keys broken so I bought an anker keyboard.

It's the one mentioned in this review:

My problem with it is the same as the problem #1 in the review, the keyboard doesn't have a escape key.

The place where esc should be is an empty box symbol which you can see in this image:



You have to press fn + box to escape. I'm trying to remap it with KeyRemap4MacBook but I can't figure out how. The review mentions that it should be possible. Any assistance is appreciated thanks.
The fn+home key combination works as Esc.
