+----------------------
+The following sections explains all about the physical keyboard and the OS interrupts.
+But, a whole lot happens before that. When you just press "g" the
+browser receives the event and the entire auto-complete machinery kicks into high gear.
+Depending on your browser's algorithm and if you are in private/incognito mode or not
+various suggestions will be presented to you in the dropbox below the URL bar. Some
+browsers like Rockmelt R.I.P even suggested your Facebook friends. You are going to
+type "google.com" so none of it matters, but a lot of code will run before you get
+there and the suggestions will be refined with each key press.
