If you know the term/idea you are looking for, then using the unit index is your best starting point. You may not find the exact term or phrase, but if you choose a term close to the one you are looking for you might be surprised. The unit index is identical to the traditional index in a book, except it indexes page headings only.
To view the unit index, click on the index button . The following index will “scroll down ”:
The list is sorted alphabetically and grouped under the letters of the alphabet - just like a normal index. To go to a page, move your mouse over the heading, for example “Barriers to trade”, and click with your left mouse button. The index will close and you will be taken to the “Barriers to trade” page.
To scroll down the index - to get to see the other letters of the alphabet - use the scroll up and scroll down arrows. These are the gray up and down arrows shown at the bottom of the index (see right).
Moving your mouse over either of these arrows will start a “slow scroll”, clicking on either of these arrows then scrolls at “turbo” speed! You can slowly, or rapidly, move between the letters of the alphabet using these scroll buttons.
