Controls are functional elements of the captured window: buttons, edit fields, drop-down lists, check-boxes, and so on. The Dr.Explain automatically recognizes controls upon screenshot capturing and create annotated callouts   for them. Generally you must just add some descriptive text into control descriptions to complete the help topic for a captured application dialog or a window.

 

You may see a list of annotated numbered controls on a window screenshot page.

 

 

There are two control states: visible (active) and invisible (inactive). Visible controls are displayed on screenshot picture in a form of numbered callouts and they are also listed in the main content of the topic.

Each control is assigned a rectangular area on the screenshot. The Dr.Explain uses control areas to create separate screenshots for controls. You may setup the control area in Control Rectangle Setup dialog.

 

You may rearrange controls, update their properties, and setup their visual settings by several ways: in the main content Editor or in the Designer mode.
