Questions
Can I use regular expressions?
Yes, toggle the regex mode to use full JavaScript regular expression syntax in your search pattern, including capture groups and backreferences in the replacement string.
How do I replace all occurrences at once?
Enable the global flag (on by default) to replace every match in the text. With global off, only the first match is replaced.
Can I use capture groups in the replacement string?
Yes, when regex mode is on you can reference capture groups with $1, $2, etc. in the replacement string. This is useful for reordering or wrapping matched text.
Is find and replace case-sensitive?
By default yes, but you can toggle case-insensitive mode to match regardless of letter case.
