keynavish (and the original keynav) use a different cursor movement system, as they work with a grid that you can recursively split/move to be centered around the target position, but yes, the end result is more or less the same as the qmk feature.

One advantage you get with this method is that you can e.g. bind a key that sets the grid size and position to match the active window, which you obviously can't do in keyboard firmware (example: https://lesderid.net/keynavish-demo.webm).
