Hi JT
You could achieve almost the same effect using a character style (say,
char_highlight) with a background shading. Before printing you would need to
replace your char_highlight style with, say, char_hidehighlight which
doesn't have the shading), and afterwards swap back - Find > Replace will do
this, but you'd probably want to set up a macro.
There is a trick to setting up the shaded character style - apply the
shading (Format > Borders and Shading) to some selected text, then create a
new character style with the text still selected.
