copy/paste single keyframes in dope sheet

hi,

i´d like to copy and paste single keyframes or only their values within the dope sheet as i was used to do it in fusion.
e.g. i have animated the rgb-gain-values of a colorcorrect-node and there are several keyframes along the timeline. now i wanna copy the values of keyframe xxxx and paste them to frame yyyy.
and i´d like to do it inside the dope sheet WITHOUT using the properties-bin!!
ctrl+c/ctrl+p doesn´t work, neither "edit->copy->….."!!

i´m runnning nukeX 6.2.1
any hints?

THANKS A LOT!!!
