Inserting keyframe problem

I have been trying to follow this tutorial http://www.youtube.com/watch?v=FAZFfLmbD2k
but I have this problem. Every time I hit the
i key to try to insert a keyframe nothing happens.
Am I doing something wrong?

when you say nothing I assume you mean you don’t get a menu.
is your object selected/highlighted, and is your cursor in the 3d view pane?

yea I didn’t select the model. Thanks for the help.
