Hey, folks. This is the first in what is surely to be a long line of requests for help customizing the notmuch emacs UI. In this episode, I'm trying to add a function to the default keymap in notmuch-search-mode. Here's what I tried to do: (add-hook 'notmuch-search-mode (define-key notmuch-search-mode-map "A" 'notmuch-show-mark-read-then-archive-thread) ) However, when I tried to use it, I got the following error (from *Messages*): notmuch-show-get-tags: Search failed: "^Lmessage{" Does anyone know where this error is coming from, and how to get around it? I could just be going about modifying the keymap the wrong way, so if anyone has better suggestions about how to do it, I would love to hear it. If there's a different way to *modify* a keymap, as opposed to adding a key to the map, I would be interested in seeing that as well. Thanks for the help. jamie.
