Dialog (Choice Type)

Use a dialog choice to display a secondary window that contains a dialog from which the user can specify parameters and invoke the action corresponding to the choice or cancel the action.

Use ellipses (...) after the textual label of a dialog choice.

Use ellipses after a choice in a menu or on a push button that causes a secondary window to be displayed, if the secondary window gathers additional information required to complete the requested task. For example, provide a Print... choice to allow the user to specify print characteristics before starting the print operation.

Do not use ellipses if a choice results in immediate action. In some cases, the action may be to display a secondary window that supports interaction with the user. For example, do not use an ellipsis on the Help choice, even though the help information is displayed in a secondary window.

Do not use ellipses simply because a confirmation message is displayed.
