Windows Help lets you display information in a pop-up window that appears whenever the user chooses a hot spot such as a word or a phrase or a graphic (see Chapter 10, “Adding Graphics”). A pop-up window is a window that appears on top of the main Help window and contains a topic.
You can use pop-up windows to display hints, notes, or any other type of supplementary information. A pop-up window can contain text, graphics, or hot spots (jump hot spots, pop-up hot spots, or macro hot spots). However, if you have a hot spot within a pop-up window, the first pop-up window closes when the user chooses the hot spot. In other words, you can only display one pop-up window at a time on the screen.
Note:
The procedures for creating pop-up hot spots are exactly the same as those for creating jump hot spots with one exception: the text for pop-up hot spots is formatted with a single underline and jump hot spot text is formatted as double-underline. Therefore, if you are familiar with the material in the previous section, you may want to skim the information in this section.
