The quickest way to get to the top of the guide is to press the mic button and say "top" or the name of the channel you want to go to e.g."BBC1"
Pressing the "Home" button whilst in the guide will take you to the date field but pressing the guide button, contrary to what was said in the previous post, will on the first press take you back to where you entered the guide. So if it was, say, ITV2 you were watching when you hit the guide button you would enter the guide at the line for ITV2. If you then scrolled through the guide pressing the guide button will take you back to the line for ITV2. A second press will exit the guide.
