I'm glad you found something that works for you. A friend used a similar technique of mashing the right and left control keys with his palms, but unfortunately after a month or so he discovered this hurt his hands too. I'm of the opinion if you're regularly pressing keys on the keyboard without using the tips of your fingers and/or thumbs you're doing it wrong.
