Fill out scanned forms with GIMP

I don't know what I did wrong when I first tried to use GIMP to insert text into a scanned form, but I came away with the impression that it's designed to add a very limited number of potentially very fancy text-images to a given image, and not a sufficient number of simple text-images to fill out a form. But I just gave it another shot, and found that its text tool makes it a snap: just select the text tool, click on the image where you want to insert text, and enter text in the box that pops up.  When the pop-up box is closed, the text appears right where you told GIMP to put it, and you can adjust its font and size in the text-tool window, and watch the effect on the text just inserted.
