A great thing is that they’re very seldom not also in one of the app menus. Memorizing cmd + ? (Help menu search, sorta like Spotlight for the app and can find any standard menu items) is often a lot easier than remembering a bunch of other commands, and great for discovering them. Another great thing is they’re generally quite consistent across apps, so memorizing one is usually applicable system wide. And another great thing is that if you don’t like the defaults (or have a menu item you wish had a shortcut in the first place), they’re almost always configurable.
