Photoshop CS4 Help Needed

[TZ250]

Guys, I just bought CS4 Design Premium. How do I select one of my layers and fill it with white? I have a project that I'm working on. I know it's easy to do, if you know how to do it! ;)

I can use a brush, but there is a better way.

TIA.

I'm sure Kevin and or Matt can jump in here and give a little advice.

first select the layer in the layers window, then use the rectangle marquee tool and and highlight the entire canvas. select your color and use the paint bucket to fill the selected area. Hope that helps.
