Figure 1-14:

A “What’s This?” button, identified by a question mark (?), is available in this sample dialog box.
The button with the question mark is called the What’s This? button. As the name implies, it answers the
question “What the heck is that thing?” that’s likely to pop into your mind from time to time. To use the
button, click it. The mouse pointer gains a question mark. Next, within the dialog box, click the item
you’re wondering about. An extra large ToolTip appears, giving you more information about the item.
Unfortunately, the What’s This? button isn’t universally available. And not all items that you click will
have Help text associated with them. When the button is available, however, it can certainly come in
handy!
