Collapsing multiple cursors to the last location

#1

I am using Cmd-D to select and then edit a bunch of things. Now I’m done with those, and I want to carry on selecting more things further down the document. When I press Esc, the multi-cursors collapse to a single cursor in the original location. I understand why this is the default, but in my situation, I need the cursor at the last selected location so I can carry on with my editing from where I left off.

I’ve tried Shift-Esc, but that doesn’t work. Is there a shortcut or some way to make a shortcut for this?

This is straightforward to do with a plugin:

# User/single_last_selection.py
import sublime
import sublime_plugin


class SingleLastSelectionCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        view = self.view
        sels = list(view.sel())

        if not sels:
            return

        # Always take the last selection
        last = sels[-1]

        view.sel().clear()
        view.sel().add(sublime.Region(last.a, last.b))

        view.show(view.sel()[0])

I have now demoted single_selection to Shift-Esc:

[
    {
        "keys": ["escape"],
        "command": "single_last_selection",
        "context": [
            {
                "key": "panel_has_focus",
                "operand": false,
                "operator": "equal"
            },
            {
                "key": "overlay_has_focus",
                "operand": false,
                "operator": "equal"
            }
        ]
    },
    {
        "keys": ["shift+escape"],
        "command": "single_selection"
    }
]

I’m having trouble with this key mapping, because it has hijacked the normal Esc behavior in menus. I thought I would be able to resolve this with panel_has_focus = false, and that does work for the e.g. Find Panel. But it hasn’t worked in other places: I can’t dismiss the Go To Anything panel/menu/etc with Esc anymore.

Is there a context I can add to resolve this? I only want my key mapping to supercede the default when focus is in the main editing view.

Edit: Seems like also adding an overlay_has_focus check resolves that. Hopefully I don’t find any other edge cases…

OK, I’ve found one more situation where remapping the Esc key is causing problems. The snippets contextual menu is no longer dismissable with the above keymap. I don’t see any other has_focus contexts, or anything about menu in the available context keys. Any other ideas?

Instead of playing whack-a-mole like this, can I just change the TextCommand to do the default thing if there are no selections, before the return?

Does adding { "key": "num_selections", "operator": "not_equal", "operand": 1 } to the context work? This is what the built in single_selection command uses.

Hey, that works! Incredible, thank you very much!
