A '''keyset''' or '''chorded keyboard''' (also called a chorded keyset, ''chord keyboard'' or ''chording keyboard'') is a [[input device|computer input device]] that allows the user to enter characters or commands formed by pressing several keys together, like playing a "[[chord (music)|chord]]" on a [[piano]]. The large number of combinations available from a small number of keys allows text or commands to be entered with one hand, leaving the other hand free. A secondary advantage is that it can be built into a device (such as a pocket-sized computer or a [[bicycle handlebar]]) that is too small to contain a normal-sized keyboard.

A chorded keyboard minus the board, typically designed to be used while held in the hand, is called a [[keyer]]. [[Douglas Engelbart]] introduced the chorded keyset as a computer interface in 1968 at what is often called "[[The Mother of All Demos]]".
