For a mouse-first OS, there sure is a heavy dep on keyboard modifiers. Day to day it doesn't bother me so much, and I even like some of them, but so much functionality is hidden with no mouse-based option. Opt-Shift-V? :/

Windows does this much, much better. I can't think of a feature where you need to use the Windows key to modify the options presented in the GUI (though the Windows key has some unique shortcuts). I'm sure someone else will correct me.

Apple has a concise list of keyboard shortcuts/modifiers listed here: https://support.apple.com/en-us/102650
