Alternatively, you can press and hold the [Ctrl] key and press one of the following mouse buttons:

◦ Pictures of the pan, zoom and rotate actions for each of the knobs.
◦ A row of numbers which correspond to each of the knobs.
◦ A horizontal sliding bar.
7. To manipulate the contents of the viewport, click the number which corresponds to the correct knob. Then slide the bar horizontally with the mouse to position the part.
