Davinci Resolve: Move polyline radius handlers separatley on macOS I'm using Davinci Resolve 16.1.1.005 on macOS 10.15.3 (Catalina).

I'm creating a simple polyline. I want to move one of the radius handlers separately without causing the other radius handler to mirror the movement.

I've tried using the modifier keys Cmd, Alt, Shift and Ctrl and combinations of them. As far as I know is Ctrl the right key. But Ctrl + click causes a right click on macOS.


Can I switch the modifier keys?
Does another keyboard mapping help?
Am I missing another modifier key?
Can I change the behaviour in some settings?
Is it not possible on macOS?
I assume, since you use the terminology "polyline" that you are in the Fusion page of Resolve.  Furthermore, since you say "radius handler," I assume you're asking about controlling the softness of a double polyline shape, and not talking about manipulating the normal bezier curvature handles.  Also, to be clear, Fusion polylines behave differently than the power windows found elsewhere in the Resolve interface.

One method of controling Fusion double polylines: 


First, activate Double polyline by clicking the outlined "D" icon if you haven't already.
Select all points with Shift-A
Hold the "O" (offset) key and click-drag in the viewer.


There are other ways to control double polylines. More information can be found in the DaVinci Resolve user manual.  As of version 16.2, the relevant pages start at 1298.

Key bindings in Resolve's Fusion are customizable, but not out of the box.  If you're determined to change them, the simplest way would be to use stand alone Fusion, which has a built-in hotkey manager in the "Views" context menu.  The compositions you create in standalone Fusion are easy to copy-paste into Resolve Fusion (but know the difference between Loaders and MediaIn nodes; Savers and MeidaOut nodes).

Alternatively, you can install the Fusion plugin package manager, "Reactor," which is available here, and install Andrew Hazelden's "Resolve Essentials" atom, which includes a script to edit Resolve Fusion keybindings.  Personally, I'd leave them alone, though.
