# Featurettes:
#  - "replace" will complete the original text for editing
#  - completing priorities will cycle through A to Z (even without
#    menu completion)
#  - list and listall will complete +<project> and @<where> from
#    values in existing entries
#  - will complete after + and @ if typed in message text
