Got Creative Cloud? Use InCopy to Convert Notes to Acrobat Comments
One of the things I pushed for when Creative Cloud was announced was the inclusion of InCopy. Besides being a great content editing companion program to InDesign it also has some features that even InDesign doesn't have such as text macros and some editorial tools. My favorite and probably the most overlooked is the ability to export a PDF and convert the notes to PDF comments.
Here's how it works.
Open the notes panel in InDesign (Window > Editorial > Notes). You can now add notes anywhere you have text and those notes will flow with the text. Just click the new note button on the bottom of the panel A small note marker will appear in the layout.
After saving the InDesign file, open it in InCopy (that's right, just open the INDD file using the File > Open command). You'll see an alert when you open the file because you don't have any InCopy content in the file. Just close it. In this case you don't need any InCopy content since we're not going to edit the document.
Your layout should look the same as it does in InDesign but you won't have any editing tools available. Again, that's okay.
All we want is a PDF so just as you would in InDesign, choose File > Export > Adobe PDF (print). Note that you won't see anywhere near the number of choices of export formats that you would in InDesign.
Here's where the "magic" happens. There's an item in the export dialog that I have long wished was in InDesign:
