My problem is that I use A LOT the "*", "+" and "-" keys. How I can simulate these keys in a compact or tenkeyless keyboard?
Please, don't tell me to buy a separate keypad...

And, no, the keypad keys are not the same of the main keyboard...
Thank you!

P.S.: Ok, why I want to buy a tenkeyless keyboard? I would like to try to have the mouse in a less uncomfortable position...
