crtl-m for me! i like to map my keys with the keywords i have in my head (control + Mode). i really like how you put it in that last sentence. though i main my macbook for development purposes, my daily driver is a linux machine. i never really knew why i liked it other than i like to fuck around with different distributions... now that i see it in words, i like that the OS respects my choices. if i want to change something, i can. it's not impossible on MacOS, it's just sort of disrespectful how difficult it is to customize your experience!
