Copy/paste keyframes

What's the easiest way to copy and paste keyframes - ideally I'd easily select all parameters at a given keyframe and copy then paste to where the time cursor is.

in the timeline viewer you can select the keyframes and ctrl+drag them to another time or even to another node

this thread has some informations about copy and pasting keys

This also works in the spline-viewer BTW.

Thanks folks, some great tips there.
