Global shortcut to open folder

I very much like the Finder shortcut CmdShiftG to navigate my files. However, it is a hassle having to open the Finder every time I use it. I would therefore greatly benefit from being able to use this function from any app that is currently open, launching the nice dialog in which I can enter my folder path. Is there any way to accomplish this? The shortcut does not have to be CmdShiftG.
