Episode 2: Manipulating and Moving the 3D View Window
Notes for Mac Users, Notebook Users, etc.:
-If you don’t have a numpad, go to File, User Preferences, Input and check the box that says “Emulate Numpad.” This uses the normal number keys as numpad keys.
-If you don’t have a three button mouse, go to File, User Preferences, Input and check the box that says “Emulate 3 Button Mouse.” This will use Alt+Left Click as the missing middle mouse button.
-To zoom without a scroll wheel: Macbook (Pro) Users can pinch to zoom on the trackpad. Others should try scrolling, using the (Ctrl =) and (Ctrl -) keys, or as a last resort look under File, User Preferences, Input and expand the 3D View and 3D View (Global) categories to set a new or change an existing input for “Zoom View”.
