Gareth,
If you find yourself performing the same highlighting operations often
in your TODO files, you might want to check out the "user-maps" feature
in the Txtfmt help. The basic idea is that you can build Vim maps from
both Vim commands (e.g., motion/delete commands) and Txtfmt primitives
(e.g., insert red-bold tokens, jump to next format token, etc...) to
automate common highlighting operations (e.g., make the current line
bold-red on a blue background). The following example was copied from
the help file to illustrate the concept...

" Map <LocalLeader>rb in normal mode to make the current line bold with
" a red background.
let g:txtfmtUsermap1 =
\'nnoremap <LocalLeader>rb <<n\vI:kr,fb>><<n\vA:f-,k->>'

:help txtfmt-user-maps
:help txtfmt-user-map-examples

You might also wish to create maps for common operations such as making
the current word bold, italic, red, yellow, etc... The odd-looking
syntax of the user-maps seems to frighten some new users away, but it
actually looks worse than it is, and the examples can serve as a
pattern. Also, I'm happy to provide more tailored examples as necessary...

Sincerely,
Brett Stahlman
