Many do not know this, but you can press F11 to get a full-screen version of your web browsers. This allows for a maximum amount of room to view web pages. To access the normal browser toolbars, move your mouse to the top of the screen. When you're ready to return to the normal viewing mode, you just need to press F11 again.
Full-sceen mode is very helpful when using ITX Learning on a "netbook" or other smaller screen.
