a white hand, a cable reel or a text editing function. You can change the function of the

Palette’.

press delete on your keyboard.

delete several icons by dragging the mouse across a selection and then pressing delete. Click and drag your red lights

further to the right side of the screen.

7. You can copy the suggested program below, or select your own. To link each icon press the Tab bar until your mouse

becomes a cable reel. Click on the right hand corner of one icon until it reads ‘end’ and then click on the left hand corner

of the icon you wish to connect it to until it reads ‘begin’ and then release. A pink connecting line should appear between

the icons. You have to continue linking in this way until the line of icons is joined up.

8. If your connecting lines are black and white, this indicates that they are not active. Go into Edit on the menu bar and

select ‘Remove broken wires’ or press Control ‘b’, which is a shortcut. Then try to connect again using the cable reel.
