Some applications provide macros and support functions so that users can use the capabilities of Mail directly from within the application. For example, the latest releases of both Microsoft Excel for Windows and Microsoft Word for Windows provide macros to send worksheets and documents, respectively, directly from within these applications.
As an example of how Mail can be integrated with applications, Windows NT provides a File Manager extension to add a Send Mail option to the File Manager menu and toolbar. The Send Mail command displays all the user interface necessary for the user to send the currently selected files or executable files as file attachments to a message. The user can add message text around the file attachment, change the attached files, and address the message as usual.
