If you must use the Visual Editor the you're out of luck for now. But if not, then go to "My Preferences", select the "EDITING" tab, scroll down to the "Preferred editor", open the dropbox, select "Source editor", then scroll down and click "Save" at the bottom. That's the only editor right now that anchors its UI to the page rather than your screen. You'll be able to see and edit several lines of text at a time even in landscape mode.

You will likely also want to install this script, probably across the UCP. If this is the first personalized java script you're using, you can just copy this there as is.
