How to get back to NnnExplorer after opening file

[Purple-Tentacle]

If open vim and then open nnn in Explorer mode (:NnnExplorer), I can chose a file, hit enter and it is opened in vim. Great.
Question: How to get back to nnn to open another file?

You can use the normal shortcuts to switch to the window again (say <C-w>k if the explorer window is above).
