- My language was careless. I meant different purposes for touch

- cutting and pasting).

- Thinking about it, you're probably right. My summer secretarial jobs

- This would be true if one is viewing the screen rather than a scrap of
- scribble one's employer has placed in the input basket. I was
- thinking more of the CP/M (or MS-DOG) editor WordStar rather than
- EMACS. (Though in EMACS the more obscure commands are not bound to
- keys exactly because they're used infrequently.)

- Yes, I was attempting to generalize based principally on where various
- groups of people place their eyes while working. Personal abilities
- and habits would over-ride generalizations. Some people have little
- trouble keeping their place on paper or a screen (or finding the
- cursor!). One of my disabilities is immediate recall, so I can't use
- the UNIX vi editor, which requires that one remember whether its in
- edit or input mode.
-
- P.S. I very much liked the descriptions of the keyboards with pointing devices
- near or on the home keys!
-
- P.P.S. Early on I discarded every bit of software that used function
- keys, because I couldn't stand one key having several different
- meanings. I switched to command-driven inerfaces (XyWrite). Because
- I move around, I now use only an EMACS clone and TeX or troff. They
- also force me to to concentrate on writing rather than playing with
- formatting when I'm at a writers' block. When I write with
- WordPerfect or something similar, I press the (choke) "hotkeys" on the
- little pull- down menus--great for the absent minded.
