- I think it's a problem. I've just recently started to use emacs, and
- noticed this independently. Anything that requires a stretch of the
- fingers that seems even the slightest bit "clumsy" or "awkward" is,
- IMHO, very dangerous if sustained for long periods of time.
-
- Since keyboards vary ENORMOUSLY in the number and placement of CTRL keys,
- the degree of the problem could vary from keyboard to keyboard.
-
- Schumann crippled his hands to the point of being unable to play the
- piano by performing exercises he divised himself whose purpose was to
- increase the independence of movement of his fingers.
-
- I _will_ say that it makes a big difference just how much force and
- travel are required on the keys you press with the pinkies. The HP2648A,
- otherwise an admirable terminal, became a torture device for me simply
- because the keys were heavily sprung to a a degree which was perfectly
- acceptable for centrally placed keys and inner fingers, but far too great
- for keys pressed with an outward-extended pinkie.
