I have a local branch where I'm doing same major table architecture work and thought I had broken keyboard navigation 😄 . Would you mind also fixing the left/right navigation in this same file?

Hmm, I did not even know it was a thing. Sure.

It only is on the content table(s) that display a tree structure.

Yeah, I found it.

Btw, rows inside BulkRenameTorrentFilesTable seem not to be selectable at all, so I'm not sure how navigation is supposed to work there.

BulkRenameTorrentFilesTable is an abomination of copy/paste. It should have extended TorrentFilesTable from the start, and I may make that change. But yeah I'm not sure BulkRenameTorrentFilesTable even has that functionality, it just has the code for it.
