Keybinding Mechanism isn't Robust

const activate = (oni) => {
    console.log("config activated")

    // Input 
    //
    // Add input bindings here:
    //
    oni.input.bind("<c-enter>", () => console.log("Control+Enter was pressed"))
    oni.input.bind("<c-s-r>", "language.findAllReferences")

    //
    // Or remove the default bindings here by uncommenting the below line:
    //
    // oni.input.unbind("<c-p>")
}

I input <c-enter> , there is no any output on developer console I input <c-s-r>, there is no any response.
