You can turn off hard keys. (sm-p600 mk1)
Sorry if this is old news but I seen a few people asking if you could disable these especially over at the clean Rom thread cause the developer included soft keys in the rom. Anyways again I'm sorry if this is old news but you go to accessibility/access control. It then walks you through a series of steps like if you want certain parts of the screen to not be affected by touch and so on. I thought this was pretty sweet. Not sure if it's for all models and firmware but worth a shot!
