The DuplicateLine Plugin
This plugin duplicates the currently selected line. It handles multiple selections (i.e. all lines with selections will be duplicated) and all selections are preserved. Just press ctrl-d, and you're golden.
There is also an alternative version that comments out the duplicated lines. Ctrl-shift-D will give you that one.
Any bug reports and/or suggestions will gladly be accepted at firstname.lastname@example.org.
