changing background colour on the current line only

[whatis neveritis]

Hi,

I worked for a company once which was using nedit, and had a macro which
would toggle the background colour on the current line between normal ->
yellow -> orange -> red -> normal.

This was really handy to tag the areas of code you were working on,
especially when editing a few select lines within thousands of lines of code
(i.e quick small bug fixes).

Is this a script available somewhere? else I can't seem to find the macro
subroutine to change the background colour.. it shouldn't be too hard to
rewrite such a macro.. any pointers would be appreciated.

Cheers.
