Amacro key is akeyboard key that can be configured to perform custom,user-defined behavior. Many keyboards do not have a macro key, but some have one or more. Some consider a macro key to enhanceproductivity by allowing them to do operations via a single key press that otherwise requires slower or multiple UI actions.
Custom behavior typically involves one or moreuser interface (UI) operations such as keystrokes andmouse actions.[1] For example, a macro key might be configured to launch a program. Agamer might configure it for rapid-fire.
Some earlyPC keyboards had a single key located on the lowest row of keys, either to the left of theZ key or to the right of the rightcontrol key. Sometimes it was treated as abackslash, but its behavior varied. It generated a specialscan code so that a program could associate unique behavior to it.
Around 2010, some mice had a macro button with a similar utility.
