Will do -- I'll add the smaller changes as separate commits before the
addition to the manual.

I re-read your first email and realized you actually answered my
question there -- the only way to create multi-key sequences (eg "C-t n
p") is to chain keymaps. Ie, what I'm trying to do above simply isn't
meant to work (it doesn't work with an interactive prompt, either).
Sorry for the noise!

Or I could dig into it myself :)

It actually wasn't that confusing, I was just looking in the wrong
place. The definition of "next", for instance, looks like this:

(defcommand (next tile-group) ... )

The second atom is put into the "class" slot of the command struct. It
indicates the group types under which the command is valid (as far as I
know there's only tile-group and floating-group). This is how so many
commands get disabled in floating groups. `command-active-p' checks if
the current group and the class slot of a command match up. Hence the
"minor modes" TODO in the comments that function.

I'm going to add a bit to both the manual and the docstring of
defcommand, you can take a look when the pull request comes through.

Agreed.

My guess is it will change very rarely. Let's leave it in both places.

My pleasure, I'm glad to be able to contribute! I hope to continue
providing fixes/features, and this was good background research.
