Wouldn't it be nice if you could get rid of all those toolbars so that you could see more of the screen? Well, you can do just that quickly and easily. Just press the F11 key and the document that you are viewing will appear full screen without (most) toolbars. F11 is a toggle, so you just press it again to make the toolbars reappear.

Don't forget this second part because when there are no toolbars on the screen, you won't be able to do anything else. So just remember press F11 to make the toolbars disappear and press F11 to make them reappear.
