Guidelines for button labels
• Use clear, concise labels.
• Use one-word labels where possible.
• Avoid using the labels "Yes" and "No." Use verbs that describe the associated action (for example, "Cancel," "Delete,"
"Discard," or "Save"). This approach helps users quickly and easily understand what happens when they click the
button. If necessary, include more descriptive text elsewhere on the screen (for example, in an application message).
• Use "Cancel" to give users the option not to proceed with the associated action, or to stop an action in progress. Use
"Close" if there is no associated action other than to dismiss the dialog box.
• Avoid using symbols or graphics in labels.
• Avoid using punctuation in labels.

Alert dialog boxes
Use alert dialog boxes to notify users of a critical action such as turning off the BlackBerry device or an error such as typing
information that is not valid. An exclamation point (!) indicator appears in an alert dialog box. To close an alert dialog box,
users can click OK or press the Escape key.
Best practice: Implementing alert dialog boxes
• Include only an OK button. This button should be highlighted by default. When users click the button, the dialog box
should close. To provide users with multiple buttons, such as an OK button and a Cancel button, use an inquiry dialog
box instead.
• Allow users to press the Escape key to close the dialog box.
• Use a concise, descriptive message to explain the situation that prompted the alert.
• Avoid phrasing messages as questions. Use statements instead.
