Where is the feature with little arrow at the edge of lister

Help & Support

Hi,
first of all, I must apologize for my bad english and will try to express myself as well as possible.
My question: I have opus 9.0.0.7 and there is one thing that I'm missing.
When youre in the lister, lets say in the detail-mode and then if you browse along your folders and then if you want to go back to the previos folder there was the possibility to go to the edge of the lister with your mouse and then at the edge a little arrow appeared. And then if you do a right-click on the arrow you go back to the previos folder and if you do a left-click on the arrow you go one folder above in the directory-tree.
Can somebody please tell me where in the preferences I can find the option to activate this feature?
Thanks, opalocca.

See part 2 here:

[Can I add a '..' item to go to the parent directory?)

Or, use the preferences filter - the word "button" finds the setting easily enough...
