Other tools do exist for using the mouse with your keyboard, but this is the first one I’ve ever found that brings up a grid and lets you click in the grid.

Other software lets you move the cursor left, right, up, down, and click, but that will never be faster than just switching to the mouse. I’ve used some before and they feel like a painful crutch.

Instead, Mouseless lets you click immediately in any location, making it even faster than switching the mouse. You can practice clicking with it using https://humanbenchmark.com/tests/aim .
