Using the Control Panel

If you look at the display produced by the Control Panel you can see in the top

left-hand corner a box containing the word 'Mode' followed by a number. This

sets the screen mode which the computer will use when it is switched on. You

can change it by clicking within the box or by using the '+' and '--' keys on the

numeric keypad to increase and decrease it. In fact, all of the options discussed

below may be changed either by using '+' and '--' to increase and decrease

values by one, or by pressing SHIFT at the same time in which case values will

be altered in steps of ten.

Below 'Mode' is the 'TV' option. This allows the position of the picture the

computer generates to be moved up and down on the monitor. It is equivalent

to the first parameter of the *TV command. The 'Interlace' option controls

whether the video interlace is on or off; you can change it by clicking.

In the next box down are three keyboard options: 'Delay', 'Repeat' and the Shift

status. The first sets the time delay before keys which are held down will

automatically repeat (in hundredths of a second). The second sets the speed

with which such keys will be repeated. The final option controls whether the

Caps Lock light is set to CAPS LOCK, SHIFT CAPS or NO CAPS.
