Below a step-by-step example on a Mac (Windows would be very similar).
I first launch TextEdit (which resides in your Applications folder), and create a little RTF file; in this example, I save the RTF file as copyright.rtf on my desktop. The contents of the RTF file is some centered text. It’s some copyright message I want to sprinkle through my document.
I create a new InDesign document, and create some frame.
In InDesign, if the Script Label palette is not visible, I make it visible through its menu item, Window – Utilities – Script Label. On older versions of InDesign, the palette is in a different spot.
E.g. in InDesign CS it’s here:
In CS2 you’d find it under the Window – Automation – Script Label menu instead.
Then I select the frame and type the word subscribe in the palette:
As soon as I hit the Tab-key or click somewhere outside the palette, a File Selection Dialog pops up. I use it to select the RTF file I just created.
The frame auto-imports the content of the RTF file.
I create a few copies of the frame and move them around a bit – for the sake of argument. All the copies are automatically subscribed to the same disk file, copyright.rtf – they ‘inherit’ that behavior from the first frame.
Here, I also have made a small change to copyright.rtf in TextEdit but I have not yet saved the modified file (I added -2006).
As soon as I hit ‘Save’ in TextEdit, the frames auto-update:
That’s All For Now, Folks!
Hope it works well for you.
