The brain is an amazing thing!
I've often marveled at how our brains work. I can dial a desktop phone about as fast as I can 10-key on a keyboard. But have you ever noticed the keys on the two are set up opposite of each other?
And those paragraphs written with no vowels- you can still read them because your brain fills in the missing letters.
I found this today - it's really pretty amazing. It's a half-keyboard. To type on the other "half", hold down the space bar. I was finding that I was hitting the right keys, but forgot to hold the space bar. I think I could get it with practice! I first tried it with my left hand only because the point is having your other hand free for using your mouse, writing, etc. Then I tried typing with my right hand. I was a little better at that.
