As far as I can tell, it's not a keylayout but rather a CyanogenMod-specific enhancement to make Android work more like a desktop OS when used with an external keyboard. The problem is that it acts as a system-level override for those keybindings so that they're not passed to applications such as remote desktop clients. I've considered trying AOKP to see if it does the same thing.
I'm interested in getting a Nexus 10, especially if someone releases a keyboard cover similar to the one for Surface, as a lightweight laptop replacement, especially when used to access a Windows machine via remote desktop, but I have such a heavy dependency on ALT+TAB in my day-to-day habits that it would be pretty annoying to have that key take me to another Android app instead of switching Windows apps. Not a show-stopper, but definitely an annoyance. Hopefully standard Android 4.2 doesn't do this...
