This covers binding Cmd+Opt+[Arrows, F, C], which is all I use:

    defaults write -g NSUserKeyEquivalents -dict-add \
        "\033Window\033Move & Resize\033Left" "@~\\U2190" \
        "\033Window\033Move & Resize\033Right" "@~\\U2192" \
        "\033Window\033Move & Resize\033Top" "@~\\U2191" \
        "\033Window\033Move & Resize\033Bottom" "@~\\U2193" \
        "\033Window\033Fill" "@~F" \
        "\033Window\033Center" "@~C"

Equivalent to manually binding in System Settings -> Keyboard -> Keyboard Shortcuts -> App Shortcuts

Ah, looks promising, and I bet I can figure out how to add the rest with that as an example and some light Web searching.

I use all of those except center, plus Cmd+Ctrl+[left, right] for top quarters left and right, and Cmd+Ctrl+Shift+[left, right] for lower quarters left and right.

Thanks!
