How to pan the view in Blender?
Suppose neither Shift or ShiftAltLMB do not work. What is the reason for this?
Unless you have changed your mouse settings, you use the middle mouse button to move in the 3D view, not LMB. Middle mouse to orbit, shift -> middle mouse to pan, and ctrl -> middle mouse to zoom.
I use CtrlNumPad 4 and CtrlNumPad 6 (arrows) in the number pad to pan left and right.
Use CtrlNumPad 2 and CtrlNumPad 8 (arrows) in the number pad to pan up and down.
If number pad is not present, Navigate to File -> User Preferences -> Input -> Emulate Numpad.
Shift Alt LMB
isn't supposed to do anything. $\endgroup$
