Question about the "search_options" argument to mark_all_occurrences() and mffind2().
When I did the macro record to find mark_all_occurences(), it gave me this:
mark_all_occurences("text_to_search","I?M",'2','0','4','0','1','0','1','0');
Here the "search_options" is "I?M". I think these options are documented in the documentation for mffind() in the "Help". It says what "I" is "Ignore case" and what "M" is "Limit search to marked area", but there is no documentation for what "?" means in search options.
So what does "?" mean here?
