Working with graphics
Dr.Explain is exceptionally useful for authoring help files with many screenshots and technical illustrations.
The built-in screenshot capturing tool analyzes the internal structure of captured windows or web forms and automatically creates numbered annotations for all significant GUI elements: buttons, fields, options, menus, toolbars, and so on. All you have to do is add text descriptions for them to complete the window annotation.
A simple screenshot is just a plain snapshot of a window without any annotations or callouts, while an annotated screenshot allows you to customize the appearance of the screenshots, bullets, and labels.
