Can I control the order of keyboard layouts in the system menu? 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:


IMEShortcuts
MLSwitcher2
Karabiner


My suggestion would be to create the same shortcut and use digits (i.e. 1, 2, 3, and 4) to differentiate them.
