Is there a way to decrease the sensitivity of the Toshiba C55 keyboard. I must have an incredibly strong aura. Should my hand hover over the keyboard, it chooses a letter or two and enters them at a place of its choosing. Or, even worse, it "selects all" and deletes everything I've typed. This happens nearly every time I use the keyboard. I know that I should save periodically, but every 2 minutes seems a bit excessive. These things have happened three times while I've typed this small bit of text. Please help!
