Hi All;
Here is a very early stage proposal to provide tagging macros for
notmuch show mode.
The idea is that user defines a mapping from single key to a sequence of
tagging operations. It might be nice if there as some kind of pop-up
menu, or at least a prompt, but I didn't do that so far.
The advantage of this rather than just writing lots of little lambdas is
that it combines adding and deleting, and it could be done via
customize.
As provided, the code should just paste into .emacs, and with a little
editing into notmuch-show.el.
