Disable *all* Scene View camera navigation shortcuts? (scroll wheel + arrow keys still active after clearing shortcut manager)

Hi there,

I’m trying to work out a way to totally disable the scene view’s camera navigation shortcuts- I’ve cleared everything I can in the shortcut manager window but the keyboard arrow keys and the mouse scroll wheel are still causing it to dolly/pan.

I’m working on an editor tool for the scene view that requires a locked camera and I’d ideally like to use those key/mouse bindings as my own shortcuts for various tool functionality.

Anyone run into this before? Maybe I’ve missed something really obvious!

thanks
