Fusion Page Keyboard Mapping

I am trying to dive deeper into using fusion. I have found that you can nudge the things in the viewer with the arrow keys. This would be awesome for precision and is what I expect coming from After Effects
I can nudge position up and down. But left and right don’t work because in resolve that moves forward and back one frame. Checking this in the standalone it works great and I love how you can hit TAB and use left and right to nudge rotation as well!
I tried changing the keyboard shortcuts in the fusion page through the resolve preferences. But that seemed to have no effect.
I just tried again with VERSION 15.0.0B.046, I work on a windows machine and on a mac.
I have even tried accessing the keyboard settings through the Reactor script but I can't "override" the mapping for Fusion using the left and right arrow as moving the playhead.
I am fine having nudging by frame be the fusion default of [ and ] while inside the fusion page. Nudging position etc. is much more useful.
It seems like the keyboard mapping is not fully implemented into the User preferences yet?
