I can definitely do that. But as a comparison notmuch-search-get-result and notmuch-search-find-thread-id "work" in any buffer in the sense of returning nil but not complaining so perhaps the current version is more consistent. Plausibly a comment and an explicit nil case would be clearer for the other modes. Best wishes Mark
