Can you reprogram the motorola-droid-razr-m screen buttons? Does it require Rooting? I'm not a big fan of the Droid-Razr-M's screen buttons (missing the menu and search buttons, but includes a Programs button (which is a waste b/c you can long hold the Home button for that).

Since those buttons are actually on the screen, can you reprogram them?
Would it require rooting the phone?
I'm not sure this would be helpful, but I love this app called Button Savior, which provides on-screen access to many of the functions you would find only via hard buttons.  You can activate it by a simple swipe, or by pressing a very translucent button that's always on the screen.  Some of the functions do require that you have rooted your phone, but not all.
