We didn't choose it, it is internal to prosemirror: https://github.com/ProseMirror/prosemirror-commands/blob/master/src/commands.ts#L746

If it's a prose mirror default, chances are that it's expected by end users, let's keep it this way.

I guess that the the only behavior that should be addressed is related to the GUI selection.

Regarding Ctrl + Enter I was not aware of it, how did you choose this shortcut ?

Should we override it?

Should we mimic the behavior of ckeditor?

I don't know, ideally we should align with something that most users would expect. Regarding Ctrl + Enter I was not aware of it, how did you choose this shortcut ?

select some preformatted code snippet (👼) + switch to normal text block => keep line breaks and the whole block change to normal text

My expectation regarding the selector is that:

If I select a part of preformatted text and style it as "text", the selected block should be converted

However, if I'm on a line, esp with my carret at the beginning of the line, when I switch my style to "Text" , I don't expect the previous bloc to be converted, I expect that, starting this point, I will have "text"
