No home key on newest build

[nevergonnauseth]

Alright I am using a TP2 on USC with the latest build of android reference. The only problem is the old builds used the power button for a home key, this version doesn't have one. Power button turns off the screen and locks it, same as call end key. Back, Windows, dialer and volume buttons all work the way they should though. Any idea how to fix this? It makes using android a pain.
