Comment 2 for bug 388314

But there is a problem with the tree view. It tries to open *files* in nautilus while moving down the list of files using arrow keys! which the Nautilus should not.
Rather the item selected should just change , and the enter key should open the file.
I think this is the reason the arrow keys are at present not allowed.

So for this to work, the no-auto open needs to be fixed, and that is a separate bug. Unless that is worked out, this bug cannot be fixed.

*But I'm confirming this bug,for a later fix, because the behavior can bring better usability* .

So maybe the people interested in this bug could file a separate bug for what i have mentioned.
