Sample browser: How to jump to root directory?

I know how to navigate upwards from folder to folder repeating FUNC+LEFT ARROW.

But is there any shortcut to jump from every level directly to the root directory?

I know on the M:S it’s hold the back button (in contrast to just tap the back button) to jump to root.

I would hope that something similar was on the DT … did you try to hold down the FUNC+LEFT ARROW combo ?

Nope, this doesn‘t work.
