To create retime markers
- Select the object(s) with animation you want to retime.
- In the Graph Editor, select all channels you want to affect, then click
in the toolbar or select Edit > Transformation Tools > Retime Tool. This enables the Retime Tool in the graph view area.
- Double-click in the graph view to create retime markers around segments of the animation curves you want to modify. (Or create a single marker if you want to move all curves in time.)
A retime marker is added each time you double-click.
