How to insert copyright line of text

Greetings! I am loving museScore. I use it as an aid to my songwriting.

I have been attempting to enter copyright information into a score. I have found the "copyright" menu under Create>Text>copyright, and it does open a panel at the bottom of my screen. The panel shows basic word processing tools, including font selection, but there is no place to enter the actual text!

I find nothing in the handbook. Any help?

I am using Windows 8.1, and MuseScore v. 1.3.
