I need to change the name of a group of files. They are pictures that were named 100_4083.JPG through 100_4242.JPG. I want to rename them to something more descriptive. On a PC I would highlight them all by clicking on the first on, then shift-click on the last one. Then, I would shift-right click on the first one and give it a new name. It would rename them all to name(0), name(1), etc. How do I do this on a Mac?
