"Show/Hide Editors"... what does this do?

In the key commands apparently pressing Shift + Alt + E shows or hides “Editors”. This appears to be a blank region at the bottom of the arrange window… I’ve clicked about and tried the usual things but either I’m an idiot or it doesn’t seem to actually do anything… My only thought is it’s maybe somehow tied to stuff in NEK and has no functionality in stock Nuendo?

What is it for? What can it do? Why is it there?

Example here:

For Chord Tracks (NEK).

Hah thanks, glad to know I was right and not just being a dumbass!

Kinda strange that the window is still there… Oh well, mystery solved.
