R help - Jun 2004 - Mozilla search engine plugin for R java search applet?

I'm interested in adding a toolbar search for my locally installed R 
documentation.  I've pursued doing it myself, but have gotten in over my 
head and thought to ask here if anybody else has done something like this
before I continue this path.

Some things that might be relevant:

An example of an R search engine

I'm using Firefox on Windows, but I suspect that's not relevant.

Javascript bookmarklets might also be relevant.
