Does these events exist in HTML/JS? (onredo, onundo, onautocomplete, onsort, onformchange and more)

Question

I recently went through w3schools complete list of events to learn them all: https://www.w3schools.com/jsref/dom_obj_event.asp

However, some days later I came across some different events that weren't listed there: https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes#:~:text=onabort%2C%20onautocomplete%2C%20onautocompleteerror,ontoggle%2C%20onvolumechange%2C%20onwaiting

Those events include: on- autocomplete, autocompleteerror, cancel, close, cuechange, emptied, sort (and then somewhere else I found redo, undo, formchange and forminput)

After searching for tutorials or explainations to those events, I found nothing but more strange looking events and I was left wondering, are these events even real? I wonder if anyone has any information about any of these events or where I can find a "COMPLETE" list of "ALL" events that are possible to use in JavaScript / HTML
