    // - This is a helper to retrieve the ActionAndArgs from the keybindings
    //   for a given chord.
    // Arguments:
    // - keymap: The AppKeyBindings to lookup the ActionAndArgs from.
    // - kc: The key chord to look up the bound ActionAndArgs for.
    // Return Value:
    // - The ActionAndArgs bound to the given key, or nullptr if nothing is bound to it.
