Ha, ha! I came to Geekhack to find information about my new TE, and to shill for the TE forum I set up, and when I go back and read this whole thread I see you guys already found my TE review, and briefly gossiped about me! I'm honored.
In my review I made a comment that the ? was the only key that switched from one hand to the other. Some of you said this was wrong, so I'm wondering if you could clarify. In normal typing, all the letter and number and punctuation keys are in their normal position, except that the quote key was moved down a row and the question mark key was moved to the left hand. What else is changed? The backslash key? That doesn't count to me because I don't count that as punctuation. I guess the hypen also moved to the left hand; I might have mentioned that, except that I find it much more useful in the upper left, as now I can hit it without glancing.
Anyway I'm typing this now on my TE and I like it very much. The quote and question-mark keys are the hardest changes to get used to, but honestly they aren't very hard at all. I also have trouble remembering not to flick my right hand outward when I want to hit the backspace key, but that too is becoming second nature.
I don't plan to remap any of the keys at this time, although changing the left space bar to something useful is appealing because I exclusively use the right thumb for spaces. One thing I have done is to create a keyboard layout which includes all my programmer symbol keys under my left hand (parens, dots, dashes, brackets, ampersands, etc.), so I can access them using the AltGr key, which is a tip I was given in the comments to my review. Maybe I should map the left space bar to AltGr; then I could hit left thumb + left finger keys to get all my programmer symbols.
So thanks again, y'all, for inviting me to GH -- I wish someone would have left a comment on my review for me to come here! I would have found you all earlier! I've long been an input enthusiast (Fingerworks, AlphaGrip, assorted ergos) and this forum will be a new home for me.
