Gotcha, thanks. Seems to be a near variant of a SPDT toggle switch, Single Pole Double Throw. Can't tell if it is technically an electrical symbol or an electronic symbol.
It's worse when you alternate between Apple's larger USB keyboard with numeric keypad (which has wider Control, Option, and Command keys) and the laptop keyboard (which jams in a fn key before those three), and your pinky gets some form of PTSD from hitting the wrong button!
They have Function, Control, Alt, Option, Command and Shift.
Regularly I forget which one is which so I just start spamming them all.
And I can never remember what ⌥ is supposed to mean.
