To give yourself more editing room, you can toggle the content window into full screen mode. You can toggle back and forth easily from one mode to the other without saving the content.
To toggle between regular and full screen mode:
Edit a content page (wiki, forum post, blog post).
On the enhanced text editor menu bar, click the Toggle Fullscreen Mode button. Notice that the content area consumes all the available browser area.
To return to regular mode, click the Toggle Fullscreen Mode button again.
