Frequently Asked Questions
How do I use regex capture groups?
In Regex mode, use parentheses to create groups and $1, $2, etc. in the Replace field to reference them. For example: find "(\d{4})-(\d{2})" replace with "$2/$1".
What does Whole word mode do?
It only matches the search term when it appears as a standalone word, not as part of a larger word. "cat" matches in "I saw a cat" but not in "concatenate".
How many replacements does it make?
All occurrences are replaced, not just the first one.
