Using sublime text 2 on windows 8, I've set my key-bindings to:

[
{
    "keys": ["ctrl+alt+f"],
    "args": {
        "id": "repl_f#",
        "file": "config/F/Main.sublime-menu"
    },
    "command": "run_existing_window_command"
},
{
    "keys": ["ctrl+shift+enter"],
    "args": {
        "scope": "selection"
    },
    "command": "repl_transfer_current"
}

]

But when I press "ctrl+shift+enter" I get the following error. Does anyone know how to resolve this?
