Pan moves the view parallel to the current viewport plane.
Pan is modal(it stays active until you right-click or select another command).
To constrain panning of any viewport to a single axis, hold down the SHIFT key. The pan is constrained to the axis you first move while the SHIFT key is down.
To accelerate panning, hold down the CTRL key.
You can also pan by dragging in a viewport while pressing the middle button of a three-button mouse. This lets you pan without turning on the Pan button.
Procedures
To pan a non-Camera viewport:
Activate a Perspective or Orthographic viewport.
Do one of the following:
Click Pan.
Press CTRL+P.
Press the middle mouse button.
Drag in the viewport in the direction you want to move.
To accelerate panning:
Hold down the CTRL key as you pan.
To constrain panning to a single axis:
Hold down the SHIFT key as you pan.
The pan is constrained to the first axis you use.
If you drag vertically at first, the pan or orbit is constrained to be vertical; if you drag horizontally at first, the constraint is horizontal.
The Zoom Extents All flyout and the Full-Screen toggles remain visible. These controls aren't specific to Camera views. Clicking Zoom Extents All affects other kinds of viewports but does not affect Camera viewports.
