If anyone is trying to reach mouseless nirvana on Windows, I maintain a tiling window manager[1] and a hotkey daemon[2] (though you can bring your own thanks to the architecture choices I made), the former of which provides a very robust event subscription system which you can integrate with using any language of your choice.
One of the cooler parts of my little mouseless ecosystem is that I automatically have different keyboard layers (QMK style) activate depending on which application is currently focused, saving me a whole bunch of time fumbling around with obscure hotkey combinations for changing layers![3]
