- Except that the CLI command can do more. How many 10-20 keystroke
- command lines are there? (Okay, how many *useful* ones?) Now, how
- many menu selections are available?
-
- What's more, you're the one who's making invalid comparisons. I, at
- least, am not (not necessarily) arguing a comparison between a UNIX (or
- VMS, or similar) command-line and menu selections. I'm arguing a
- comparison between menu selections and short bucky-bit command
- sequences (clover-key sequences on the Mac, control-key on UNIX, for
- example).

-
- But the rabid GUI types don't use the keyboard for anything *except*
- text in the WP. I'm talking about (say) selecting "Save" from a menu,
- versus (say) typing control-X control-Q.

-
- This is an excuse for crippling those of us who *have* learned to type?
