“What's This?” Explained

Many applications are distributed with context sensitive help. This is a short piece of text associated with most of the options in an application which can be accessed by right clicking the mouse on a control, and selecting “What’s This?” from the menu that appears.

Figure 26: Mouse Over Help

 


Clicking on the “What’s This?” item displays some helpful text in a manner similar to a large tool tip.

Figure 27: Example of Tool Tip

 


Determining whether an application supports context sensitive help is very straightforward. If help is available, a “?” button will appear in the title bar. Clicking it turns the mouse cursor into a question mark; subsequently clicking a control within the same dialog will display the same context sensitive help as the “What’s This?” option.

It is generally potluck whether an application supports context sensitive help or not.
