保存为winfuncs.sh

保存在以下路径，如下：

/home/appleyuchi/CommandForShortCut/winfuncs.sh

chmod u+x/home/appleyuchi/CommandForShortCut/winfuncs.sh

Applications=>Settings=>Keyboard=>Application Shortcuts

1、Add

2、Command中输入/home/appleyuchi/CommandForShortCut/winfuncs.sh showdesktop

点击OK

3、弹出对画框，按下windows键+D即可
