I think I can safely say now that I decently adjusted to the TB. I can pretty much always expect to be at 40 or more wpm on ordinary stuff as long as I remember how to place my hands and arms to start. I don't drift away nearly as much. While I was over 50 usually on a regular keyboard, this is fine and, best of all, it will only get better as I practice with the TB. Amazing after just 5 days!
I still have a ways to go for various symbols and even those I know, as well as numbers, I have to get used to doing automatically. At least the ones I could handle well on a regular keyboard. When I do mess up, it is most often z s l on Dvorak (all in the same column). Also a ; on the other side. Finally, k often trips me up. On qwerty, these problems would be p ' ? / and a z and the v key.
Somehow, when typing the letter with the asterisk, I sometimes get the asterisk. I guess I must be putting some pressure on the space bar? It's rare.
There are some things that are a little more difficult with the TB, but not much that won't fall more practice. One of these is the volume on my computer. Sometimes I'd have my old keyboard on the desk and, if I suddenly needed to change the sound volume, I could just F11 or F12 key at the top of my apple keyboard without grabbing the whole thing. Just one finger. But it seems changing volume with the TB, while simple enough if already typing on your lap, is more complicated if it is just lying, unused, on the desk since it takes two hands rather than 1 finger.
QUESTION: Also on my apple keyboard, the F1 and F2 keys change the screen brightness. I can't seem to control that on TB. Any ideas?
