FWIW, my “jk” mapping is also global, as is my C-[ mapping. Karabiner FTW. In all seriousness I haven’t found a way to manage a “jk” mapping that so correctly and quickly handles all cases of input in anything else, on any platform. (Except of course built into the keyboard) Autohotkey can kinda sorta do it, but it takes a lot more code for an inferior result sadly.
