This is a bit of an aside, but I play a lot of Playerunknown's Battlegrounds with a regular team of friends. That game has a fiendish amount of keyboard commands, even related to regular movement. Many of them can be accessed through sub-menus, but that puts you at a competitive disadvantage when things happen fast. I've figured out that I just don't have the hand-eye coordination to move in four directions, activate the scope, zoom the scope, lean left and right, aim the gun and fire it during the exact right milliseconds. So I unloaded the "lean left and right" actions from my right hand to my feet, using a set of rudder pedals intended for a flight simulator. I then unloaded some of the esoteric menu options from keyboard shortcuts to a Stream Deck with user-friendly (works even for six-year olds) picture interface right in front of me. Improved my performance considerably.
