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.
