F8 is right next to F9, which is super important for loading autosaves in Bethesda Softworks' games, so thats a big affirmative over here.
If I played a game requiring something like that I'd learn it quick.
I previously bought an all-black mech keyboard with no key labels which looked sleek but I didn't like it, swaped the keycaps out two days later. Switching to a new keyboard is probably a good time to keep them until you get used to it!
