Adding "onclick" event to links in text areas
Sorry all, I discovered my question was invalid.
I was able to user onclick directly in the "full html" text area, and while the value of the attribute didn't show in the view source, it was working.

I'm not sure if D6 always handles onclick in full html text areas or not. I choose to believe there is something causing this in my theme.

Thanks for your attention!!
