+Commands which take a folder name
+.RB ( inc ,
+.BR refile ,
+.BR scan ,
+.BR sortm ,
+\&...) accept the folder name in two formats: \*(lq+folder\*(rq or
+\*(lq@folder\*(rq. \*(lq+folder\*(rq specifies a folder underneath
+the Path defined in your profile; e.g., with the usual
+.RI \*(lq "Path: Mail" \*(rq,
+\*(lq+folder\*(rq tells nmh to use
+\*(lqMail/folder\*(rq. \*(lq@folder\*(rq specifies a path
+relative to the current folder specified in your \*(lqcontext\*(rq
+file; e.g., with
+.RI \*(lq "Current-Folder: inbox" \*(rq,
+and the same profile, \*(lq@folder\*(rq tells nmh to use
+\*(lqMail/inbox/folder\*(rq. If folder begins with \*(lq.\*(rq or
+\*(lq/\*(rq when using \*(lq+folder\*(rq, the folder is interpreted as
+a specific path to a directory on the filesystem rather than a
+relative folder location.
