What tutorial? 

Alt/Option + 4 shows the alpha channel in the Composition, Footage, or Layer Panel. Pressing Alt + 4 again returns the viewer to RGB. If your whole composition panel turns white, then you have a solid layer in the composition because a white Alpha channel equals no transparency, and black equals transparency.
