+occurrence of some text in a buffer (possibly narrowed) or region, and
+simultaneously have other occurrences edited in the same way.
+
+You can also use Iedit mode as a quick way to temporarily show only the buffer
+lines that match the current text being edited.  This gives you the effect of
+a temporary @code{keep-lines} or @code{occur}.")
