How to use the Dialog widget:

The demo dialog is activated by clicking on the "Trigger Dialog" button.

While the dialog contains focus, the tab order will wrap inside the dialog. If the dialog is modal, it is not possible to move focus to the main page until the dialog is closed.

If the dialog is movable or resizable, the dialog user interface will include buttons that allow these actions to be performed by keyboard. To do this. move focus to the button, and use the arrow keys to move or resize the dialog.

To close the dialog, press Escape.
