Frequently Asked Questions

How do I use capture groups?

Wrap part of the pattern in parentheses and reference it with $1, $2 and so on. Finding (\w+)@(\w+) and replacing with $2/$1 swaps the two halves of every match.

What does whole-word matching do?

It requires a word boundary at each end, so searching for "cat" will not match "category" or "concatenate". It is the fix for the classic replace-all disaster.
