Does this support regular expressions?

Yes. Toggle 'Use Regex' to use JavaScript regex patterns. This supports groups, lookaheads, quantifiers, and character classes.

How do I delete all matches?

Leave the 'Replace with' field empty. All matches will be removed from the text.

No. By default, the search is case-insensitive. Toggle 'Case Sensitive' if you need exact-case matching.

In regex mode, use \n to match newlines. For example, replace \n with a comma to join all lines.
