Modifier Keys

I must be the only Mac user on earth that can't remember the symbols for all the modifier keys --- why is the command key the only modifier that is blessed with it's symbol on the physical keyboard? Why aren't the modifiers just documented with their names in the menus?
Seems a little like hazing - or some other kind of secret knowledge that only real Mac users are supposed to know.

Are regular users supposed to know about modifier keys at all -- or are they supposed to stick to the mouse only?

Sure I can look them up -- but for some reason - my feeble mind can't remember what arrow thing is vs stair step thing.
