This is something that has irritated me since windows/mac's started hiding the UI/shortcut hinting in favor of a "cleaner" interface. UI discoverability was a huge part of human/computer interaction research in the late 70's/80's. If you look at the menu's in win3.1 for example you will see that nearly every menu item has both the alt-menu, keystroke, shortcut as well as the global keyboard shortcut to the right of the menu entry. AKA alt-f, s was save, but some applications might have also put another keyboard shortcut to the right say 'ctr-s' or something. This means that your average user who kept clicking the file->save menu could see that alt-f,s (via the underlines) would perform the same function without the mouse, or just that there was a simple shortcut. Windows gradually removed this, and in the xp timeframe you only saw the shortcuts when the alt key was pressed while the menus were active. This of course defeats the purpose of sticking the shortcut in the users face everytime they click the menu, and the concept has stuck around to the point where in win10 google is pretty much the only way to discover shortcuts if the even exist (which is hardly rare). This is part of the reason I stick to the classic interface in win7, with the right tweaks its still puts the keyboard shortcuts in your face. I only wish that modern UI designers spent a day or two actually reading the human/computer guidelines/research before calling themselves experts..
