I have just finished the video titled: Control Interfaces. In it, I was given instructions on how to emulate the numpad. This feature is important for me because I have a Macbook, and the keyboard lacks a numpad. The video asked me to go to File -> User Preferences to turn on ‘Emulate Num Pad’. At the point, I got lost because I cannot find the File menu. After restarting Blender, the File menu showed up.
You could gone to info bar and changed it
see the previous lecture he told the way to get back the layout
