Describe the feature

In #5574 ctrl-w hjkl were set up to move between panes and ctrl-w HJKL to move a whole pane in a direction. I'm hoping for a variant of these commands that lets me move a single editor from one pane to another pane.

Unless I missed it, I don't think there's a command for this at the moment. I think having that command without any default keymapping would be wonderful.

If applicable, add mockups / screenshots to help present your vision of the feature

Not just vim. To support Sublime Text keybindings ctrl-shift-*number* would require a similar command, but for an nth pane.

I don't see any PRs open for anything similar, I'd like to take a swing at it.

So analogous to ActivatePane and ActivatePaneInDirection, would MoveToPane and MoveToPaneInDirection work? Or a bit more verbose MoveItemToPane and MoveItemToPaneInDirection?

Ready for feedback #21760

Question: should we close the pane if the last item has been moved from it?

• Sublime doesn't, but Sublime's empty pane is just an editor w/o the tab.
• When the last item is moved with a mouse, Zed closes the pane, Sublime doesn't.
• So closing the pane w/o items is more consistent with the rest of the Zed's behavior

Example bindings:

            "alt-shift-h": ["workspace::MoveItemToPaneInDirection", "Left"],
            "alt-shift-l": ["workspace::MoveItemToPaneInDirection", "Right"],
            "alt-shift-k": ["workspace::MoveItemToPaneInDirection", "Up"],
            "alt-shift-j": ["workspace::MoveItemToPaneInDirection", "Down"],

            "ctrl-shift-1": ["workspace::MoveItemToPane", 0],
            "ctrl-shift-2": ["workspace::MoveItemToPane", 1],
            "ctrl-shift-3": ["workspace::MoveItemToPane", 2],
            "ctrl-shift-4": ["workspace::MoveItemToPane", 3],
            "ctrl-shift-5": ["workspace::MoveItemToPane", 4],
            "ctrl-shift-6": ["workspace::MoveItemToPane", 5],
            "ctrl-shift-7": ["workspace::MoveItemToPane", 6],
            "ctrl-shift-8": ["workspace::MoveItemToPane", 7],
            "ctrl-shift-9": ["workspace::MoveItemToPane", 8]

The latter should be added to the "base_keymap": "SublimeText" defaults. May I do it in the same PR? How do those work? Just edit default-*platform*.json after the comment, right?

Should I also add vim defaults? If so, which exact?
