Hi,I recently set "org-use-fast-tag-selection" to nil in my configuration. This meant "org-beamer-select-environment" stopped working since it assumes that "org-set-tags" will launch the fast-tag-selection mechanism when it has set "org-tag-alist" to it's special value.
Fix: Explicitly set "org-use-fast-tag-selection" to t in the let*-construct in "org-use-fast-tag-selection", as is now done with "org-fast-tag-selection-single-key".
Greetings, Anders Johansson
