Also, I'm using LayAuto software for window placement on a large display (split display in various sized grids - let me know if you want me to share my defaults). This is absolutely invaluable, as otherwise you spend most of your time arranging windows. Another one I've used and likes is Magnet, but it didn't allow me to customise the split and the keyboard shortcuts. Source: over 2 years ago

Then, I can only suggest http://hammerspoon.org/ and then you can start implementing window movement using it https://www.hammerspoon.org/go/#winmoveintro. Source: 12 months ago

MacOS doesn't do this natively, but you have options: - If you just want to move windows around with some degree of keyboard customization, go for Rectangle. - If you want more control, such as sizing a bunch of windows at the same time, use Slate. - If you can code and want really high degrees of customization, you won't go wrong with Hammerspoon.

Both of those can be replaced by the open-source Hammerspoon (actually a significant number of the things in this thread can, including BTT). Source: about 2 years ago

Depending on what you want from KM, Hammerspoon may be a good alternative. You can also look up on AlternativeTo for other options. Source: over 2 years ago
