47      <p>
48        To run the AT-SPI Validator Plugin, select an item in the Application Tree View.
49        The validator will generate the report with respect to the selected
50        item and all of its descendant widgets in the tree hierarchy.
51      </p>
52
53      <p>
54        After selecting an item, choose a validation schema in the combobox and press the <cmd>Validate</cmd>
55        button to start generating the report. If you want to cancel the execution, just press the <cmd>Validate</cmd>
56        button again.
57      </p>
58
59      <p>
60        The generated report is interactive. Therefore, you can double-click any error found to check which of the target
61        application widgets is causing it. The corresponding widget will then appear selected in the <link xref="desktop_tree_view">
62        Application Tree View</link> and highlighted in the target application.
63      </p>
64      <p>
65        If you want to save the generated report in your system, just click the <cmd>Save</cmd> button.
66        To clear the validation screen, press the <cmd>Clear</cmd> button.
67      </p>
68      <p>
69        To get more information about an error in the generated report, make sure the corresponding item is
70        selected and press the <cmd>Help</cmd> button. It will open a Help Page in your default browser.
