The prompt appears on all
NSSave objects (or all
NSOpen objects if this property is on an
NSOpen instance) in your application. By default, the text in the default button is “Open” for an Open panel and “Save” for a Save panel.
Use short words or phrases, such as “Open,” “Save,” “Set,” or “Choose,” on the button. The button is not resized to accommodate long prompts.
