Editing Turbo key

The '''Turbo''', '''Fast Repeat''' or (simply) '''Repeat''' key or button is a [[modifier key]]
that makes key repeat when held down, or modifies repeat rate from slow to fast.

==Focus keyboards==
The Turbo key on some keyboards from [[Focus Electronic]] is a modifier used in conjunction with the [[function keys]] to modify repeat rate for the keyboard.

Keyboards include:
* [[Focus FK-2000 Plus]]
* [[Focus FK-5001]]
* [[Focus FK-9000]]

==Typewriters==
On typewriters, keys such as the [[Space bar]], [[Backspace key|backspace]] and [[Return key|Carriage Return]] don't normally repeat.
The Repeat key enables repeat function on some keys: which ones it affects are different from typewriter to typewriter.

==Game controllers==
A similar Turbo function is found on game controllers, making buttons repeat.
There can be a lever for all or a group of buttons, each lever for an individual button or an additional repeating Turbo-button for a button. There is sometimes a rate control.
Some levers have multiple steps between Single, Turbo and [[Autofire]], where Autofire in this context means that repeated button press inputs are created without the button needing to be pressed.

* [[Autofire]]
