= Input Context = An input context represents a client to Fcitx server. Usually, an input context may be mapped to an application, a window of the applicaiton, or a global context of the display server. When a input context has focus, it means that this specific client is actively used by user and the window of the input context should also have the focus.
输入上下文表示 Fcitx 服务器的客户端。通常，输入上下文可以映射到应用程序、应用程序的窗口或显示服务器的全局上下文。当输入上下文有焦点时，意味着这个特定的客户端被用户主动使用，输入上下文的窗口也应该有焦点。
