Thanks, this seems like a nice feature.

Seems reasonable, since 'e' is already taken in tree mode. Can you
update the file devel/emacs-keybindings.org so we don't lose track of
the bindings. Also, per the contributing guide [1], please add some brief
documentation to the emacs docs in doc/notmuch-emacs.rst

Whether or not this is the right thing to do, something seems to have
broken the test suite. Perhaps after you fix the test suite, the answer
will be more clear? Or perhaps not, then we can revisit the question.

Also, we need at least one new test (ideally one per mode). There should
be some tests you can crib from in T310-emacs.sh and T450-emacs-show.sh.
In particular it is perfectly acceptable to call the toggle function
directly rather than trying to fake keystrokes.
