Frequently Asked Questions

Enable regex mode. In your find pattern, wrap parts in parentheses — each group is numbered from left to right starting at 1. In the replace field, reference groups with $1, $2, etc. Example: find (\w+),\s*(\w+), replace with $2 $1 — this swaps "Smith, John" to "John Smith".

It wraps your search term in \b word boundaries. Without this, searching for "cat" would match "cats", "concatenate", "category". With whole word enabled, it only matches the exact standalone word "cat". This is the same as Ctrl+H → "Match whole word" in VS Code or Notepad++.
