HI,
I had a function that let me Option-Left Click and it triggered the Rename function...which normally shows up when you right click then click on Rename (or type R), then Enter.
I have used it many times to select multiple files at once, option left click and it pops up the Rename function.
All of a sudden...it stopped working. I don't know what changed, but it won't work, and I can't remember how I built the function in the first place. i tried repeatedly and couldn't figure out how to rebuild it.
