How this exercise works

The pages within a module are 'random access': you can jump around them in whatever order you choose.

However, some materials are best approached in a particular sequence. This is done using a 'step-by-step' presentation. This 'exercise' type is not evaluated, that is, you are not required to input answers that are then evaluated.

A 'control bar' allows you to control the display of the steps. You can operate the control bar and move through the steps of the presentation using the mouse or the keyboard.

Using the mouse

• Click on the button to return to the first step in the sequence.
• Click on the button to go to the previous step in the sequence.
• Click on the button to go to the next step in the sequence.
• Click on the button to go to the last step in the sequence.
• You can jump to any step by selecting its entry in the pulldown selector list.

Using the keyboard

In this exercise you can select steps using the keyboard. You can see a list of the keys that are available and their functions in the control panel.
