{“Here’s a neat little trick you can use in Panther’s Save and Save As dialog boxes.
Invoke either command and click on a grayed-out entry in one of the columns that appears in the resulting sheet. The words in the Save As field will change to whatever you clicked on.
This can be a big help when you’re saving a bunch of documents in series — “,”, for example. Just click on one of these Important Documents and all you have to do is change the number at the end of the title rather than the entire entry.”}
