Windows Address Bar Shortcut?

I'm not aware of a direct shortcut, but I use Win + B then Shift + Tab.

Ok... I lied. I binded the above to an AutoHotkey shortcut. But that still counts as using it, right? :)

I think you are looking for this !

Alt+D

Works in browsers too !

If you mean the Windows explorer address bar, simply hit F4, no need for AtuoHotKey.
