The meta key is a key on some keyboards, normally located adjacent to the spacebar that can be used to perform special functions when combined with another key. It originated on keyboards for Lisp computers in the 1960s, and its use continued on Sun computers where the key was marked with a diamond shape.

Today, on modern computers, keys such as the Windows key (on Microsoft systems) or cloverleaf key (on Apple systems) fulfill the traditional function of a meta key.
