1.在Python\Lib\idlelib下，建立一個ClearWindow.py檔案（沒有時就建立），內容如下：

　　2.Python\Lib\idlelib下修改config-extensions.def ，在末尾添加如下內容：

1[ClearWindow]enable=1enable_editor=0enable_shell=1[ClearWindow_cfgBindings]clear-window=<Control-Key-l>

　　3.重新Python的IDLE，在options選項中就可以看到增加了Clear shell Window Ctrl+L，即清屏的快速鍵為：Ctrl+L
