When using pop-ups, you will need to provide the same information in an accessible format. Context sensitive help can be accessed through a Help action on the form. Instead of using a text pop-up, provide a button on the form which will display the information when pressed. The button label should be consistent with the text pop-up label. If the pop-up is used to provide more information about an input field, add static text on the form to explain the field.
Testing Check the product to ensure that it complies with accessibility requirements.
Open the pop-ups with the mouse. Verify the same information is available through a help button or static text on the form.
