Is it possible to close whatever app you're in without having to back out all the way to the home screen? Say I have a website and I clicked several links in it, if I want to close it I'll have to press back and it'll take me back through the pages until it exists the browser. Alternatively I could look at the open tabs and close that tab the press back to get back to the home screen but I'm looking for a faster way and the browser was just an example.
