Where is the hidden place to copy paste keyframes in Fusion

everyone aways says, if you want to do something other than just cutting video USE Fusion. Here I am in Fusion, is duplicating / copying keyframes just not a thing?

Like most things Resolve, multiple ways to do most things.

Easiest? (depends on desired result)
If you hover your mouse pointer over a keyframe, it changes color.
Holding the Cntrl key (Windows) and dragging will copy/paste (duplicate - like Alt in edit page)
Holding Cntrl and clicking multiple keyframes then dragging will duplicate the keyframes selected.

It sounds counterintuitive, but don't use the keyframe panel for adjusting keyframes, use the spline editor.
It's easier to select keyframes, to copy and paste them in there. And the ctrl+drag method will also work very clearly if you do.

Okay thanks guys
