Shortcut for the menu bar!

I think the keyboad is so much faster than the mouse and I try to use it for everything I do. Unfortunately, some command just don't have any keyboard shortcut or sometimes, I don't happen to remember that rare shortcut that I use once a month. I finally found the solution: a keyboard shortcut that gives you access to your menu bar from which you can choose any command with your arrows. The shortcut is "Ctrl - F2". On a laptop, you might have to add "Option" if the F2 button is assigned to something else (such as brightness). When you press that key combination, the  menu is highlighted and from there, you can navigate through the menus with the arrows.
