Frequently asked questions
How do I replace text without matching uppercase variants?
Enable Match case. With it disabled, the search treats uppercase and lowercase forms as equivalent.
How are replacement tokens handled?
They expand only when Regex and Expand replacement tokens are both enabled. Otherwise the replacement is inserted literally, including dollar signs.
Can I undo a replacement?
Yes. Undo restores earlier working results during the current session. Reset Result returns to the original input.
