You can synchronize the frame range of your project between the Dope Sheet and the Curve Editor. This is useful when you’re using both of them to edit your animation curves and keyframes at the same time. To synchronize the frame range:
1. | Right-click anywhere on the Dope Sheet. |
2. | Select View > Synchronize frame range. Any changes you now make to the frame range displayed in the Dope Sheet are applied in the Curve Editor too, and vice versa. Zooming in and out in either also zooms the other view. |
TIP: You can also do this by clicking the Synchronize Frame Range button at the bottom of the Dope Sheet.
