KeyMapper is a free utility software for PC from indie developer Stuart Dunkeld. It is an open-source remapping tool that lets users change and re-assign specific keys and functions on their keyboard. It boasts a simple and intuitive user interface, and it can also be used to create macros to perform specific tasks like launching an app or triggering an action.

Custom keys and macros

When you open the KeyMapper utility tool, you will be presented with a virtual keyboard interface wherein you can start making changes to keys. Change one, you can double-click on in and you will be shown a prompt with a list of functions grouped into different categories like Media, Modifiers, and Commonly Used.

You can also create custom actions, such as launching a program or performing a combination of keystrokes in productivity applications. Once you have everything set up, you will need to restart your PC to apply the changes you made. Overall, it works as intended and is very intuitive to use. The only minor thing that could be noted is it could have a nicer UI design, but it's not a big deal.
