Should undo/redo be beforeInput events?

[BenjamP]

How do we determine when we need a new event? Or is everything just going to use beforeInput? This also applies to custom events if we support them, like 'checkout' event or 'save' event.

Is there any advantage to have custom events handled by the browser rather than directly through the client?

[johanneswilm]

As for custom events: We already have ways to listen for key clicks in Javascript and it is fairly easy to have set up one way of listening to a series of key combinations and then initiate various things, such as "Save", "go to next", "close", etc. .

Maybe there are other good use cases for this that I cannot think off, but it seems like that should then be a spec of its own and not depend on whether or not there is a contenteditable=typing element on the page.

I will close this for now, but please reopen if this has been misunderstood.
