This module offers you many instances of context-related help. This help can be divided into the following five main types:

Help on exercise interfaces

The functions of each exercise type and the way you are expected to work with it are fully documented in individual help files. Where such help is available you will see a button such as this located at the start of each exercise type section:

Clicking on this button will open the relevant help file in a separate window. Note that a single exercise page can have sections containing different exercise types, each of which will have its own button.

General notes on an exercise or a presentation page

Some exercise pages or presentation pages may offer additional explanatory material, usually relating to the content of the page and not its functionality.

Where this is the case, you will see a button such as this located close to the top of the page (the author of the page may have given this note a different text):

Clicking on this button will open the relevant document in a separate window.

Related document sections

An author may offer a 'related documents' section containing information about other materials relevant to the current page. These sections can appear on presentation and exercise pages.

• The author may have given the section a different name, for example 'Recommended reading'.
• References in this section can be classified into types such as 'book references' or 'web references', and any of these may contain hypertext links which display linked content in a separate browser window.

Glossary entries

Both presentation and exercise pages may contain highlighted sections of text, indicating that a glossary entry or some other comment of definition is available for the text in this section.

Clicking on the highlighted section will open a small popup displaying the relevant glossary entry. Clicking on the section again, on the popup or anywhere else on the page will close the popup.

Hints and tips within exercises

The author of an exercise may also have provided one or more tips or hints on completing the current exercise. These can be located anywhere on an exercise page and may contain, for example, a hint on how to answer a particular question:

Clicking on the button will open a section of the document below it containing the information. Clicking on the button again will close the section.
