If you could add one default key on the Windows Phone keyboard, what would it do?

So many times, navigating through my HTC Trophy, I find myself wanting a "Right Arrow Key" button. When I am trying to place the cursor, it isn't so accurate and I am usually to the left of where I want my cursor to be. Then I have to hold my finger and try again. It is a complete waste of time. This is my biggest gripe with the keyboard. BTW, I am a MSFT shareholder and NOK shareholder, so I care more than a non-shareholder
