Any right click plugins?

Hi all,

Rather than having "show, edit, delete" as separate links for tabular
data, I'd like to create a custom right click menu that provides those
options. I've already got onMouseOver and onClick handlers setup to
highlight the rows, btw.

I've found some standalone javascript onine that does this, but I
thought I would ask to see if Rails, or any Rails plugins, provide any
javascript that lets me easily do this. Or, if anyone has any advice
in general on how best to do this, I'd be glad to hear it.
