+Ranges
+======
+Many commands that operate on individual messages, such as
+`mh-forward' or `mh-refile-msg' take a RANGE argument. This argument
+can be used in several ways.
+
+If you provide the prefix argument (\\[universal-argument]) to
+these commands, then you will be prompted for the message range.
+This can be any valid MH range which can include messages,
+sequences, and the abbreviations (described in the mh(1) man
+page):
+
+<num1>-<num2>
+ Indicates all messages in the range <num1> to <num2>, inclusive.
+ The range must be nonempty.
+
+<num>:N
+<num>:+N
+<num>:-N
+ Up to N messages beginning with (or ending with) message num. Num
+ may be any of the predefined symbols: first, prev, cur, next or
+ last.
+
+first:N
+prev:N
+next:N
+last:N
+ The first, previous, next or last messages, if they exist.
+
+all
+ All of the messages.
+
+For example, a range that shows all of these things is `1 2 3
+5-10 last:5 unseen'.
+
+If the option `transient-mark-mode' is set to t and you set a
+region in the MH-Folder buffer, then the MH-E command will
+perform the operation on all messages in that region.
