This seems like a FAQ, but I haven’t been able to find a similar question.
How do I have the tab and shift-tab keys work to indent and unindent list elements? Currently using the tab key in the demo application (http://prosemirror.net/demo/basic.html) causes focus to move to the next element in the browser.
You use a keymap that binds them to the sinkListItem and liftListItem commands.
It looks like sinkListItem only works if there is already an indented list underneath the current list item. If that’s the intended behaviour, is there a command to indent/unindent regardless of the surrounding elements or should I try putting something together to do that?
Sounds like you want to chain sinkListItem and wrapInList (move item into sublist if already in an item, otherwise create a new list)
