Key Remapper is an app (or website) designed to allow users to remap and customize the keyboard of their computer, laptop, or other device. It enables users to create their own keyboard layouts and shortcuts, as well as to modify existing ones. It can also be used to customize the mouse and other input devices. Key Remapper can be used to assign specific applications or commands to specific keys or combinations of keys. This is useful for executing complex tasks or commands quickly, or for customizing the keyboard to the user’s individual needs. This app (or website) is available for both Windows and Mac operating systems.
X-Mouse is for mouse only, it cannot reassign keys and assign special functions to them.
