I have learned that Photoshop does not come with a "Save all" command. However, I would like to have such a command.
What I found on the web:
I read here that I can record the action of saving a file, and then associate it with a key so that I can trigger that action later using a keystroke. However, wouldn't that be the same as going through my files one by one and then using Ctrl-S to save each individual file? How can I run an action on every open file?
