I've got a large number of rtf files which I'm compiling into a help file. I'd like to be able to make a replacement of a particular term in all documents automatically. How can I do that? I've tried using a field code {AUTOTEXT AppName} and defining an Autotext called "AppName" . This works but I have to go through each document and select Update Field for each field before compiling the help file, which rather defeats the purpose. I want the changes to take place automatically whenever I change the Autotext. But how?
