Not really sure about this one, my reasoning to remove the uppercase letters was to make the cheat sheet easier to read and skim.

As a cheat sheet is not a menu and we also have the section titles, I see no benefit for keeping the Title Case of key commands. They just make the cheat sheet harder to read in my opinion.

IMO the lower-case variant isn't more appealing than the title-case variant to my eyes. But your millage may very.

Perhaps not worth a discussion but we should put some guidelines for new contributors out there, so they have something they can refer to.
