Hi [USER=69670]@IamSam[/USER]
When I retired, there were many things I could do, yet never all of them, so I still had to choose where to spend my time. As far as scripts, I only learned enough to know that I did not want to spend the time on having that expertise. The Scripts Event Manager, in my opinion, is a misnomer. It's just an Event Handler. In software, all that is is an alert that a certain System/Software Event occurred so it can be intercepted with the option of executing additional user steps. When I need that capability, I almost invariably run an Action, not a Script. There is a default Event dropdown list that is provided as shown here:

Those would satisfy many needs. It also lets you "Add Events." There are no real pointers for what events are available and the magic code or text to use when adding one. I wondered about that long ago, and a recent post made me think about it again. Most lists were woefully outdated, and some scripts that indicated they could list them did not.
I certainly was not going to write a script, so I was about to put that curiosity back on the shelf (probably forever). Then, I thought I would ask ChatGPT for a script to enumerate Photoshop's Event IDs. It instantly listed out a script, which I copied and pasted into a file, and I ran it from Photoshop. That is the extent of my scripting skills. 
So, if I ever had a major batch job that could not be satisfied by an Action yet would work by recognizing a Photoshop Event, I would know I could go back to this post as a resource to look for an appropriate Event (in theory, at least).
It was mostly an effort to satisfy my curiosity and document my findings rather than any "Aha" about its broad usage or utility.
