Thumbbar!

[edczxcvbnm]

It appears I use my right hand to pound away at the space bar but all signs point to Mr. Lefty when it comes to then demons of the Shift Key.

My right index finger, pansies

I'm generally left handed, but space with my right thumb Unless I'm eating, then it's my left thumb

Also, I use my left pinky for the shift key, except for typing smilies, for some odd reason Maybe it's because the colon's so close to the right shift making one handed smilies easier
