That worked, I'll comment on usability below.

Understood.

Yes, I have been doing this with success for sometime. Finding $ as a
regular expression and replacing with an empty box is solving my issue
most of the time. It can't be used automatically on the whole document
because it screws up the paragraphs.

What is the source of your research, the 'Regular Expressions' page of
the help file? I have studied that page so long and hard I nearly have
it by rote! It lacks useage examples.
It is significant you have used the phrase "eye of the beholder". My
background is mechanical engineering, designing and building machines
plus by Howard Gardner's 'Multiple Intelligences' measure - strongly
visual/spatial. Kword runs rings around OOo in the usability stakes,
for instance look on \d to find a digit (easily found under the Edit
button which is greyed out until the Regular Expression checkbox is
high-lighted) and intuitively \d\d\d to find a three figure number.
Kword is developing fast but has to mature on other scores compared to
OOo.

Very much so Brian, I'm pleased you have adopted me. I have a few more
curly questions for you. 8-))
