I hold on the back arrow which produces a drop down list of previous pages allowing you to skip over the ad pages etc to the previous page. Advantage of this is it takes you to your original place on the page rather than the top of the page
so its those creepy things that screech at you that have planted adware.....surely Ed's tecchies can get rid of that..... I am also hovering over the back key and going back to the page I want.
