The new Safari in Leopard can do Google talk now.
The new search in Safari is remarkable as well. command+f adds a search bar at the top and begins highlighting words as you start typing.
Of course if you don't have Leopard, this won't help you much. I'm not sure how to do what you are wanting to do in previous versions of Safari.
leopard is pre-installed on my macbook. But I really cannot use google talk.
Have you checked for any updates? I don't remember what I updated, but when I checked recently, there were several updates.
I don't have my Mac right now, but it is under the Apple in the menu bar in the upper left corner. Hope it helps
What version of Safari are you using? Click the "Safari" menu (next to the apple in the top left) and then select the first item, "About Safari".
Why would you use GTalk in the browser? Just use it in iChat. Or Adium. Anyway, it works fine for me in Safari in Leopard (when I logged in to change my settings to allow IMAP access), so I'm not sure what's happening to you. As for highlighting a word, just use Cmd+F.
