This tool opens to show a jumper. Click on the coloured square at the bottom left to change the colour of the jumper. Drag shapes from the tabbed dock below the make patterns on the jumper. Any unwanted items from the dock can be dragged into the bin. To remove all shapes from the jumper, click the ‘Clear all’ button above the bin.

Clicking ‘Reset’ undoes any changes you have made and returns the tool to its default state.
