@IsModalHelp
flag
Boolean
A modal Help document is a document that displays as a dialog box that you must dismiss before you can access any other currently open windows. Use @IsModalHelp to determine modality so you can execute a formula only when the document is (or isn't) a modal Help document.
You cannot use this function in Web applications.
