elpa-iedit - 0.9.9.9.9-2 main

This package is an Emacs minor mode and allows you to edit one 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 `keep-lines' or `occur'. To get this effect, hit C-'
when in Iedit mode - it toggles hiding non-matching lines.
