How to nudge a keyframe by one frame?

In Fusion 9 it was easy to nudge keyframes back and forth with a shortcut in the spline view but in Fusion 16 perhaps I'm not figuring it out.

Using either Ctrl-Shift or Alt-Shift I can nudge by 10 frames or .1 frame, but how to nudge by only one frame?

I'm aware as well of the TOffset, that is not what I'm looking for. I'm talking about the shortcut.

Looks like this is broken on Windows because no modifier combination nudges by one frame, but Ctrl does on Mac.

I'd call it a bug, too. In the Viewer, Ctrl+Shift+Arrow does a 1-pixel nudge. I'd expect the same to be true in the Spline View, but it's not—it does a 1/10th frame nudge.

Of course, better than simply fixing that hotkey, it'd be great if the Nudge function were exposed to the hotkey editor also so we could override the arrow keys back to legacy Fusion standards if we wished.

Agreed. I would much rather the arrows WITHOUT any modifiers to be able to nudge keyframes spline vertices.
