Hi, Alan,
For such questions you should include if you use a Mac or PC.
Looks like you are a Mac user, and a right click would be a control + click.
Check the tiny manual that came with the software, and read the help pdf.
There are some books about Lightroom that will definitely help you to get it to work.
I also just bought Lightroom, and ordered from Amazon:
"The Adobe Photoshop Lightroom Book: The Complete Guide for Photographers"
Martin Evening; Paperback; $26.40
This forum here sells a video tutorial:
