Let's say fld "bunchamoney" contains the text "You can get millions  
by going to this web site." and you want to make the word "millions"  
clickable. Make the word "hot" and associate a string of text with it  
like this:

	set the textStyle of word 4 of fld "bunchamoney" to link
	set the linkText of word 4 of fld "bunchamoney" to "http:// 
www.nigerianmillions.com"

Now lock the field and write a linkClicked handler in its script. The  
linkClicked message returns the linkText of the linked text you  
clicked on so you have to provide a variable to hold the linkText  
contents:

   on linkClicked linkTextOfTheWordIClickedOn -- (or any variable  
name you want)
     if linkTextOfTheWordIClickedOn contains "http://" then
       revGoUrl linkTextOfTheWordIClickedOn
     end if
   end linkClicked

The revGoURL command opens the url in the browser that is set as the  
default browser for your system.

After a few times of having it become obvious *after* someone tells  
you, you'll start to get a feel for what "obvious" is in the Rev  
context. :-)
