UI Spy provides two ways to select a UI item: focus tracking and hover mode. Both methods will select an AutomationElement. Once an item is selected, a rectangle is drawn around the item. The selected item is shown in each of the opened View windows and UI Automation properties for the item are displayed in the Properties window.
Focus Tracking Mode
When you use UI Spy's focus tracking, the tool follows the UI item that has keyboard focus. Common uses for focus tracking include stepping through UI items to ensure that each item can receive keyboard focus.
Hover Mode
When you use UI Spy's hover mode, you select a UI item by clicking and holding CTRL for a specific amount of time. To configure the amount of time, on the Edit menu, click Settings. Hover mode is convenient when you want to select a specific UI item.
