OS X has had this since Snow Leopard -- you can go to any application's help menu, and begin typing the name of a menu item, even if it's nested. Using the arrow keys, you can navigate down the list of results, and as you select each item, the menus expand to show you the location of the item with a large, blue arrow next to it. You can then either click the item next to said arrow, activating it -- or simply press enter. Apple had this years ago; they just made a conscious decision to keep using menus.
