Paul McCarty / DARS Coordinator // x52059 > 317 Lattimore Hall, University of Rochester, Rochester, NY 14627 > Computers don't make errors; what they do, they do on purpose.-Dale/KOTH I've been mostly planning on the P5 (which driver isn't written yet) - I don't have experience with a Twiddler, I'd wonder how easy Ctrl-Alt-+- will be to type on a twiddler. I haven't used X (yet, focusing on just learning Linux thoroughly before I add X, as I only use Windows to print on WinTel machines.) My girlfriend's disabled, and partially I'm thinking of this for her, partially for me, just have a machine "do it" without my having to always bother with the keyboard is really a good thing from MY point of view (I have enough to remember to do without having to remember to change display resolutions!) as well as from hers (she can hardly type at all, hers may have to be voice-recognition based, and to keep telling her machine to Resolution Change can sap her energy, but it can do it automatically & she can cope.) I just discussed trains off someone else's post (As good a point from you as from him!) - Elevators. Hmmm, that's another special case I haven't been thinking about. I'd think treating an elevator ride as a movement (i.e. shift to lower res) would be an acceptable answer, but that'd be configurable I think. If she's riding an elevator she's usually paying attention to her service dog, so she'd want it to stay in low resolution mode. Elevators aren't the safest places to do computer work for women, either, though I wouldn't know; I'm rather tall & male... This might just work for some folks, not for others. I'll think on it!
