Collapse All Folders in Folder tree shortcut?

Is there a way to collapse/close all folders in the folder tree in one keyboard shortcut?

If I am in a working in a folder many folders deep within say Windows and I then need to get to either the root folder or another drive then I certainly don't wish to scroll up in the folder tree.

Is there a way to do this using keyboard shortcuts?

I would appreciate any tips and suggestions.
Thx!

A hotkey with

Go ROOT=collapse

should do what you want.
