Key bindings not binding

Hi -- I purchased the Pro upgrade and edited my default.keybinding file to add the following:

        "comment" : "toggle preview",
        "key": "0",
        "modifiers": ["cmd", "shift", "opt"],
        "action": [

I also checked the "Use keybindings to update menu bar shortcuts" box in the Pro preferences pane, and then restarted MMC. But Cmd-Shift-Option-0 does not toggle preview. I also tried Cmd-Shift-P, but that continues to run Print Preview. What am I missing?

Also, is it possible to define keyboard shortcuts using the Enter key (my normal preview-toggle keyboard shorcut is Cmd-Enter)?

    You're specifying the action as an array of steps, but it's only a single step and you want it to match a menu bar item. Change the "action" value from an array to just "action" : "togglePreview:" That should do it!

    Hi Fletcher, thanks for the response, but I'm sorry to say it doesn't seem to work. I've modified as you suggested and still nothing. The menu does not show the shortcut for Toggle Preview, and the key combination does nothing. Here's my complete default.keybinding:

            "comment" : "toggle preview",
            "key": "P",
            "modifiers": ["cmd", "shift", "option"],
            "action": "togglePreview:"

    You're using "option", when the correct value is "opt".

    The documentation is here --

    It's worth taking a look at if you're having trouble.

    Thanks, I missed that. But originally I was trying to set it to Cmd-Enter. If I set the key to \\\U000A (or \\U000d) I get Cmd-backslash as the combination. What should I use for the Enter key?

    I'm not sure what the string used for specifying the Enter key is for
    the macOS. I was able to find the others through Google.

    But if all you are doing is specifying shortcuts for menu items, then
    the easiest way is probably to use the keyboard system preferences.
    This allows you to set shortcuts for any application on your computer,
    and to do it using a GUI interface.

    The keybinding file is intended for adding new commands, or for creating
    more complex commands using a series of actions. It's pretty powerful,
    but does require some experimenting to accomplish what you're looking
    for sometimes. It's a bit cumbersome if you're simply overriding menu
    command shortcuts (unless you're trying to copy a custom configuration
    to multiple machines, I suppose.)
