P: Issue adding line-wrap to text using identity plate in Print module

This request pertains to Lightroom 3.4.1...In the Print module to add text, I click the "Identity Plate" and start typing my text...the problem comes when I want to skip a line or wrap to the next line. In Scott Kelby's book "Lightroom 3", page 340, paragraph titled "Step One" it says to ."...press Alt-Enter twice to move down two lines." This is for a PC. For MAC it says "...press Option-Return" I contacted NAPP about this and they say it is a bug that Adobe needs to fix for PC users (apparently it does work for MAC users but not for PC users). Can you please fix this or tell me if there is a work-around to the problem. I really need to add more than one line of text when printing my images using Lightroom3. Thank you.
