i thought he was talking about the home button that several browsers have me bad. when you are surfing around, you are unlikely to have your hand on the keyboard. and locating the home button at least for me requires some effort. i can type without looking at the keyboard but home key is not something that can be reached easily. the bookmark comes handy because you are already likely to have one of your hands on the mouse just a matter of preference i guess. i needed this thing. i love clicking the top bar in google plus which takes you to the top and i miss it on all websites.
