In this case, my client had provided a Word document with (in the one case) content that had to be merged with existing content and (in the other case) corrections to content. I placed the Word document on the pasteboard and then worked through the document page by page either merging content or making corrections.

Each time I moved on to the next page, I ran the script to bring the place Word document along with me. Granted, I could have cut/paste, but it was much easier to run the script (which was but a couple of keystrokes away — Cmd-A to fire up my script that presents a list of recently run scripts: the one I wanted was almost always at top of the list, so all I then had to do was hit Return and there were the corrections for this page, right where I needed them.
