Sublimetext2 使用两个'；通配符'；人物

我正在尝试开发一个需要如下键绑定的包：

{ 
    "keys": [",", "<character>", "<character>"], 
    "command": "super_awesome"
}

有没有办法做到这一点

谢谢

class SuperAwesomeCommand(sublime_plugin.TextCommand):
    def run(edit, **args):
        print(args) # => { 'character': '2nd character pressed' }
