Thanks, Jeanne. The case sensitivity will certainly help. Would it be possible to activate the filter in preview mode too? I'd consider it very useful.
I had known about the code tag, however if I want to use the problematic
word in a sentence, it gets a bit messy. What about ignoring texts in the tt tag too? I understand that tt is just a formatting tag, whereas the code tag defines a meaning for the enclosed text, however I assume that the typical usage of the tt tags is to enclose eg. variable names etc. Putting the problematic text in a tt tag would not break the sentence.
