Just Do This I had the same problem in MonoDevalop, but the url in it cannot be changed. So I tried a plugin of Chrome :https://chrome.google.com/webstore/detail/redirector/pajiegeliagebegjdhebejdlknciafen We can set the transform in options of this plugin. From: ^https://unity3d.com/cn/support/documentation/ScriptReference/(.*) To: https://docs.unity3d.com/ScriptReference/$1 Then we can use Ctrl + ' to search in the documentation.
