I have a few keyboard layouts or "input sources" as the system calls them. The system also lets you define a keyboard shortcut for "Select next source in Input menu".
I had muscle memory of how many times to hit that key combo to go between various keyboards. Then after a reboot they are now in different order. Is there a way to set the order so it doesn't change?
Since you're using more than two input sources you'd be better off configuring a specific shortcut for each input source.
Without knowing the exact version of macOS you're running, there are a number of tools you could use to achieve this:
My suggestion would be to create the same shortcut and use digits (i.e. 1, 2, 3, and 4) to differentiate them.
I am facing the almost same issue I explained in here. Perhaps following the replies might help. I've already been advised to use Kawa to assign shortcuts for each language. That might help to you or someone else after me. Peace!
