Should we start with a story?

No, we shouldn't. 


But we should start with something easy. Take the toolbar at the top of almost any web browser, be it Firefox, Opera, IE or some other. They all have ('File', 'Edit', 'View', History, etc.) menus along the top of their window. How do you get to them without your mouse? Simple, first hold the 'Alt' button, now you'll notice that certain letters in the menus are underlined, this tells you which key you'll need to press next. For example, to get to the 'Tools' menu in Firefox you'll hold 'Alt+T' then you can let go of both keys. Once the menu has slid out it's a simple matter of using your UP and DOWN keys or press the underlined/highlighted letter of the option you want. 


See, simple.
