$MATCH
$&

The string matched by the last successful pattern match. (See "Scoping Rules of Regex Variables".)

See "Performance issues" above for the serious performance implications of using this variable (even once) in your code.

This variable is read-only, and its value is dynamically scoped.

Mnemonic: like & in some editors.
