You can display the tangents of only the selected channels. This can be useful if the Channel Editor is cluttered and you want to concentrate only on a subset of channels to edit.

To show only the tangents of selected channels:

1. If necessary, switch to the Animation Curve window by selecting Channels in the Channel View box, or by cycling to it by pressing F5.
2. Select one or more channels.
3. Select the Filter tab.
4. Enable Filter Tang.

   
   

   Only the tangent handles of selected channels are displayed. The tangent handles of unselected channels are hidden.
