But you don't really have to learn many keyboard shortcuts at all to get started with org-mode. TAB is pretty much all you need in the beginning.
And later on, if you decide to keep using it, you can decide to add more shortcuts to your repertoire on a case-by-case basis.
"Yank" is not specific to org-more, btw, but Emacs lingo which predates, of course, a lot of modern UI conventions. Most other names are quite straight-forward.
Note also, that it's not the keyboard shortcut that is called "yank" - the latter is the name of a functionality which you could, if you wanted so, type out in order to use it. The keyboard short is there so you don't have to, and you don't even have to remember the proper name of the function that the shortcut is for.
