How do I do a case-insensitive find and replace?+
Enable the 'Case insensitive' toggle. The search matches 'Apple', 'apple', and 'APPLE' equally. The replacement is applied to all matches regardless of their original case.
Can I use regex for find and replace?+
Yes. Enable 'Regex mode' and enter a regular expression pattern. For example, find \d{4}-\d{2}-\d{2} to match all dates in YYYY-MM-DD format. Use capture groups ($1, $2) in the replacement string.
What does whole word matching do?+
With whole word matching, searching for 'cat' won't match 'catfish' or 'concatenate'. It only matches the standalone word 'cat'. Equivalent to the word boundary in regex.
How do I replace line breaks or special characters?+
In regex mode, \n matches newline, \t matches tab, \r matches carriage return. To normalise line endings to Unix style, find \r\n and replace with \n.
