### Issue

How do I spin and otherwise manipulate the surface in the surface window

### Solution

The method for doing this is to use the numeric keypad on the right hand side of the keyboard.

First ensure that the 'num lock' is on (indicated by the 'num lock' light on the top right of the keyboard being lit). If not press the 'numlock' key on the top left of the numeric keypad.

The spinning of the surface is done with various keys (with the coloured keys in the picture below being used for manipulating the image, the others are not used) on the key pad as below. Press the keys once to move it a little. Hold the key down the continuous movement. The amount of movement in each key press is controlled by a popup menu in the surface window.

num lock | = | / | *
7 | 8 | 9 | -
4 | 5 | 6 | +
1 | 2 | 3 | enter
0 | .

The red keys rotate the image up (8) and down (2)

The magenta keys rotate the image left (4) and right (6)

The green keys tilt the image clockwise (7) and anticlockwise (9)

REMEMBER: num lock must be on.
