Add a keyboard shortcut to rotate a proof and use ctrl + mousewheel to zoom instead of shift

[#1]

Description - I didn't see any keyboard shortcut to rotate a proof and the default one from Acrobat doesn't work (Ctrl, Shift, - or +). Our line of work constantly has elements that are horizontal or upside down on envelopes and other flat proofs. 

I wish WF Proof used the same keyboard shortcut to zoom in and out with the mouse wheel (Ctrl + Mouse wheel) as it is in Acrobat so I don't have to constantly think about which shortcut to use since Proof uses Shift and the mouse wheel.

Why is this feature important to you - To easily navigate a proof using the keyboard for those of us who prefer shortcuts over the mouse to do everything. I am much more efficient in Acrobat than Proof. 

How would you like the feature to work:

Ctrl, Shift, - or +  keyboard shortcut to rotate a proof

Ctrl + Mouse wheel keyboard shortcut to Zoom in and out

Current Behaviour - No shortcut to rotate. Different shortcut to zoom in and out than Acrobat (possibly a Chrome issue, but it seems like Proof shares other shortcuts with Chrome, it just depends on if you are in the proof itself or not)
