How do I edit the spell-check lexicon to exclude certain words from the
spell-check?

The reason for this is that certain errors are not flagged as errors because
the mis-spelled word is a valid word that's included in the lexicon and
isn't flagged as an error. An example of this is the word 'for' which I
often mis-type as 'fro'. Because 'fro' is a valid word it isn't flagged as
a mistake. However it's a word I'd rarely use, if ever and it would be much
better if I could remove this from the lexicon so my mistyping of the word
'for' would show as a mistake.
