Paste From Marker
 
 
 

Pastes data from one marker to another with a global offset. To paste, move the Timeline indicator within a gap, click Paste From Marker, then select the marker you want to paste in the Viewer window. This option generates a control curve in the current gap containing the animation from the other marker with an offset to fill the gap.

When you perform Paste From Marker in a gap, handles are generated with which you can adjust the interpolation.
