Clicking on the different tabs gives different types of access to Help. Click on Contents . Notice that Windows Help has two panes. What you see in the left pane is like the contents of a book. On the far left there are two types of icons, one looks like a book and the other looks like a piece of paper with a question mark in it.
Some topics look like a book and some like a piece of paper.
When you click on a book item, you get another list of subtopics. Click on a piece of paper with a question mark in it, and you'll get instructions in the pane on the right. Now click on the Index tab, near the top on the left. The Index is an alphabetic list of topics, like the index in the back of a book. Notice the borders on the right and bottom of the left pane.
