I never perceived this as a sloppiness. Since the first time I've
read the tutorial, the notion of C-f etc. being a kind of command was
very clear to me. The tutorial has this all over the place. Here's a
typical example, of which there are many:
The following commands are useful for viewing screenfuls:
C-v Move forward one screenful
M-v Move backward one screenful
C-l Clear screen and redisplay all the text,
It even says right at the beginning:
Emacs commands generally involve the CONTROL key (often labeled CTRL)
or the META key (usually labeled ALT). Rather than writing that
Later it says:
* EXTENDING THE COMMAND SET
---------------------------
There are many, many more Emacs commands than could possibly be put
on all the control and meta characters. Emacs gets around this with
the X (eXtend) command. This comes in two flavors:
C-x Character eXtend. Followed by one character.
M-x Named command eXtend. Followed by a long name.
Take away the notion that C-f is a command, not only a key, and the
above explanation of "command extension" has no basis, except perhaps
as a historical curiosity.
So I think we should maintain that C-f etc. is a command as well as a
key sequence.
