-.SS "The Previous Sequence"
-.B Nmh
-provides the ability to remember the `msgs' or `msg' argument
-last given to an
-.B nmh
-command. The entry \*(lqPrevious\-Sequence\*(rq
-should be defined in the
-.B nmh
-profile; its value should be a sequence
-name or multiple sequence names separated by spaces. If this entry
-is defined, when an
-.B nmh
-command finishes, it will define the
-sequence(s) named in the value of this entry to be those messages that
-were specified to the command. Hence, a profile entry of
-.PP
-.RS 5
-Previous\-Sequence: pseq
-.RE
-.PP
-directs any
-.B nmh
-command that accepts a `msg' or `msgs' argument to
-define the sequence \*(lqpseq\*(rq as those messages when it finishes.
+begin with the value of the `Sequence\-Negation' profile entry.
+The default value `!' was chosen due to its similar meaning in the C
+programming language, and because it cannot be part of a user-defined
+sequence. But if your shell provides history expansion,
+you might need to quote the exlamation mark (prefix it with a backslash).
