+            Multiple commands, separated by a <em>|</em> can be
+            given in a single command line and will be executed consecutively.
+            <em>|</em> can be included as an argument to a command by escaping
+            it with a backslash. E.g.
+            <code><ex>:map \| :echo "bar"<k name="CR"/></ex></code>
+
+            Several commands process the entire command line string literally.
+            These commands will include any <em>|</em> as part of their
+            argument string and so cannot be followed by another command. The
+            list of these commands is:
