Is there a way to copy single key frames?

When I’m using the transform effect. I find myself wanting to copy a single key frame. I see an option to copy them all but not an option to copy just one.

Select the keyframe by clicking on the “pinhead”, then click on the copy icon, position the playhead on the frame you want to copy the keyframe to and click on the “paste” icon. More details in the official Kdenlive documentation in this section.
