Animating the Alpha property.

How do I make somthing fade in? I"m doing a logo, and I need to make some text fade in, but I don’t understand how to set the alpha at a certian frame and the make it appear to “fade in” later.

I think I have it figured out.

Just to make sure…
there are two ways - either use the IPO editor directly or you can press I while hovering over the material settings buttons, then set an alpha keyframe.
