Similar question here: How to get back the »open parent« button in 11.10?
However, I want always-use-location-entry to be true. So I am not using breadcrumbs.
The shortkeys, both backspace and ALT+uparrow, are quite helpful. However, since I'm mainly using my mouse in Nautilus, I'd much prefer to actually have a button present that I can click. Then I don't have to switch between keyboard and mouse all the time.
Is there a way to add this button/functionality, while keeping always-use-location-entry to be true?
Another workable solution would be to use both breadcrumbs and the location-entry; so a parent is clickable, but I can also type a path directly.
