The view menu and toolbar offer some tools to adjust the current viewport of the drawing. All these tools have no effect on the geometry of the entities of the drawing. They only change the zoom factor and the visible area (viewport).
Viewing tools are probably the most often used functions in a CAD
system. They can be easily accessed from the viewing toolbar (Figure
12). For the ones you use most, it is
worth remembering and using the hotkeys. For example to show the whole
drawing, simply press
ZA. If the command line has the keyboard focus, you need to
press the Escape key to release the focus first.

12: The viewing toolbar.
Use the two scrollbars at the right and the bottom of the drawing window
to scroll around in a drawing. If you have a wheel mouse, you can also use
the wheel to scroll up and down (hold down the Ctrl key) or left and right
(hold down the Shift key).
If your mouse has three mouse buttons, the middle mouse button can be
used to change the current view by dragging the drawing around
(panning).

Description:
Panning means moving around in the drawing. The quickest way to do so is using the middle mouse button and move the view similar like you would move a paper around: press the middle mouse button and hold it while moving the drawing around. If your mouse does not have a middle mouse button you can activate this tool instead and then do the same with the left mouse button. Click the right mouse button when you are done.
