| Interesting. SendMessageAny with CF2.dwmask set to CFM_Hidden and with
| selection set to SCF_ALL does indeed globally un-hide all the hidden
| words in the document.

 Re-hide "them"? The sub above will hide the current
selected text. You have to use an SCF_* constant, so I
guess it would be either SCF_SELECTION, or SCF_WORD.
The latter might be easier. From the docs it sounds like
you could hide any word by putting the SelStart inside
a specific word and then using

SendMessageAny hRTB, EM_SETCHARFORMAT, SCF_WORD, CF2

   It does seem to be awkward keeping track, though. If
you want to re-hide specific words I guess you'd have
to either 1) hide them by searching for the actual word
in the text or 2) maintain a list of the index of each word.
But the former requires only hiding specific spellings, and the
latter requires that you track all changes to the text in
order to hold accurate offset values for the given words.

  It might be easier to just parse/edit the actual RTF
every time you want to make changes. You'd just have
to find out what marker begins and ends hidden text.
I guess it depends on exactly what you need to do.
