Apply Scale not working

I am watching this tutorial: http://www.youtube.com/watch?v=XCEN0qQOsIA
and at 6:29 it says to hold Ctrl and press A and click on Apply Scale. Nothing happens on my screen, no hot key.
Any idea how to get apply scale? Thanks

Make sure you are in object mode.
Make sure your object is selected
Make sure your mouse is in the viewport

Hit ctrl-A and a menu should appear.

Thanks I was in edit mode
