New Templates or Preview Modes are not accessible

New templates or Preview mode is usually available for me
However I am stuck in the template selection modes and cannot
select anything or modify any of my saved templates.
Editor mode is available but I can not create a listing there.
This has happened once before and I can not remember how
I got out of it

I solved my problem. I remembered and located the (teeny-tiny-small)
dot below the templates
and held on it until it closed the page.
No longer have an issue but so very happy to have found the forum.
