CS 2...Layers...How do I open a folder?

[Stecyk]

Hi,

I am still working my way through the book The Art of Photographing Women by Kevin Ames.

On page 209, he states the following:

Zoom in to 100% Actual Pixels view. In the Strategy Map set, click the eye icon off of Strategy Blocks and Strategy Map. Click on th eye icon for Strategy Map 106%.

How do I open the folder at the top of my layers palette. I have tried right mouse clicking, double clicking, single clicking, and nothing seems to work. I am sure that this is trivial, but I am still learning my way around CS2.

Thank you.

Best regards,
Kevin
