List of Key/Gamepad Input Names - Epic Wiki

# List of Key/Gamepad Input Names

# Overview

This page will detail the internal names used for various keys and gamepad bindings. These are used primarily in the DefaultInput.ini file, as shown in the example below (Taken from the first person shooter template)

+ActionMappings=(ActionName="Jump", Key=SpaceBar) +ActionMappings=(ActionName="Fire", Key=LeftMouseButton)

(Here, SpaceBar and LeftMouseButton are the internal names to bind to the spacebar and left mouse button respectively)

For the most part, these bindings will tend to be obvious (A-Z, F1-F12 etc) but some keys may have odd or different names, hence the purpose of this document. This list will also contain gamepad bindings and touch device bindings, which are internally interpreted as 'keys'.

This is a reference document and may not be fully up to date with the latest version of Unreal Engine 4. For your most up to date list of these key names, view the InputCoreTypes.h file in 'Engine\Source\Runtime\InputCore\Classes'.
