Updating urls in property window

Hi,

I have a text box with a long list of items. Within each line of text is a hyperlink that I added by filling in that option in the properties window. Now I need to change one word of each url. I'm guessing that I'm going to have to do this manually, but I'd like someone to confirm this for me before I start plugging away at this one url at a time. I sure do wish that I'd done this in actionscript. Manual replacement is going to take all day. Is there some way to do a global search and replace that I haven't been able to find?

Thanks a bunch,
Debbie
