What?

Part of: #39519
Alternative of: #39626
Based on @mtias's suggested algorithm here: #39626 (comment)

I think pressing enter on an empty list item should backtrack one level at a time. This video is from Apple Notes as an example (I'm only pressing enter):

Screeny.Video.28.Mar.2022.at.13.50.44.mov

In the experimental new list blocks we should split lists on empty list items if we press enter.

How?

Since my first approach with a different algorithm, the indentation has been implemented by @jorgefilipecosta and I'm using one of the hooks for one of the two parts of the algorithm.

Testing Instructions

  1. Insert a new list block with any nested lists
  2. On an empty list item press Enter
  3. Should split the list and insert a paragraph in the middle
  4. If the list item we press Enter is nested it should outdent

Screenshots or screencast

Notes

  1. The handling of Enter in a non empty list item is not handled yet, as it needs more changes involving the RichText API.
  2. I've created a new hooks file and moved useIndentListItem and useOutdentListItem without making any change. The new hook is the useEnter one.

Shouldn't this be indent?

Why? It's working as expected in the video, no?

For me it was indenting for some reason instead of outdenting.

Looks good to me, but the behaviour seems to be the opposite?

@ntsekouras In a separate PR, can you do the same thing for Backspace? Gradually the list item? Worth checking how it works in list v1, I think the behaviour there is good.
