How do regex replacements with capture groups work?
Enable regex mode and reference captured groups as $1, $2 in the replacement - the classic way to reorder or wrap parts of every matching line at once.
What does whole-word matching prevent?
Replacing "cat" inside "category" - with whole-word mode on, only the standalone word changes, which is usually what a bulk edit intends.
