C-c / will prompt for another key and then dispatch depending on
that
key.
Many do.
Hmm, that would fit into the already mentioned coding-style
category.
Is it wise to do it that way?
For example M-x describe-mode fails telling about these keys.
Are reasons for this?
Yes. There are not enough keys, unless I introduce a larger number
of full-scale prefix keys. And it is much easier to remember just
`C-c
/' and then get a friendly prompt for a number of options. For
interactive use, I think this is just perfect.
Now, if you want to write programs based on these functions, then you
want to have the real command names. This is one of the reasons why I
like to have them in the manual, for look up.
