Removing strings like "[1]", "[8]" from multiple rows of text in EditPlus. I couldn't figure out how to escape square brackets, so I broke it down this way:


\b - word boundary:

Since digits are considered to be word characters, \b4\b can be used to match a 4 that is not part of a larger number. This regex does not match 44 sheets of a4. So saying "\b matches before and after an alphanumeric sequence" is more exact than saying "before and after a word".
