#### 3.5.4.10 Printing Another Message: ~f and ~F ¶

Sometimes it is necessary to view the contents of another message, while composing. These two escapes allow it. Both take the message list as their argument. If they are used without argument, the contents of the current message is printed. The difference between ‘`~f`’ and ‘`~F`’ is that the former uses ignored and retained lists to select headers to be displayed, whereas the latter prints all headers.
