When should I put ... at the end of a menu item? I seem to remember reading some rules but can't for the life of me find them.
For context - I'm adding a properties option to a right click menu and am wondering if it is appropriate to add them.
One exception to the first two answers: if the whole point of the menu command is to open a window or dialog, then you don't need an ellipsis. For example, a "Get Info" or "Properties" command shouldn't have it, even though it's opening a window which lets you edit things.
It's only when the menu command's purpose is to do something else, but it needs a dialog or confirmation in order to do it.
