[feature] Evokable Drag method

Problem

For accessibility, it would be useful to support keyboard-only draggable behavior. I've seen this where the handle has a keybinding that puts the current item into a draggable state and then the up and down arrows can be used to navigate the item up and down a list.

Desired Solution

Support a method that would put the list into this state, with passed item being the item that is being "dragged".

Additional context

I have to profess I don't remember how to do this in other frameworks. In Vue, you would bind the the draggable component to a ref, and then call the method against it.
