Does anyone know of anything out there that can be placed over the keyboard on the 755 that would then make the keys "grippy" (similar to the Centro).

The keys are very slippery and I'm finding that I type much better using my thumbnails, but I can't use them on the 755P keys. I was hoping there was some kind of keyboard overlay available that would make the keys have a little more grip to them.

Any ideas/suggestions?
