How to enable snapping animation keys in the Graph Editor, in which after use Shift + D I could move the selected keys. Key X = 0, Y = 0 exactly snap to animation key X = 20, Y = 2. And then use Shift + R to duplicate the sawtooth curve? So that after the selected key is moved, it snaps to the neighboring key on the X-axis and Y-axis.

Or it can be done only by knowing the exact coordinates of the key X = 20, Y = 2, calculate the exact offset. And after use Shift + D write the coordinates of the displacement along X and Y. And then use Shift + R to duplicate the sawtooth curve?

Maybe there are still alternative ways to make a sawtooth curve?

We do not use the Cycles modifier for a curve with «Repeat with Offset» and an indication of Restrict Frame Range End, because after the sawtooth curve, if you add new animation keys, then the shape of the initial curve changes. And the new curve repeats cyclically. But on the Influence parameter cannot be installed by the driver, and the animation keys cannot be installed. enter image description here Advantage / application snapping animation keys:

  1. Replacement / alternative of the Cycles modifier in the "Graph Editor". Manually duplicate animation key loops via Shift + R with exact binding of the start animation keys to the end animation keys of adjacent loops. Because in the Cycles modifier there is no way to put the driver or animation key on the Influence parameter. And if you put animation keys on the curve after the end of the Cycles modifier, the shape of the curve changes and another shape of the curve is cyclically repeated.

  • $\begingroup$ Did you try holding Ctrl Key while moving? $\endgroup$ Commented Jan 9, 2022 at 7:49
  • $\begingroup$ Ctrl does not give the desired result. Because it not snapped the active animation key to another animation key. The analog of snapped active vertex to any other vertex. I want the same thing with the animation keys in the Graph Editor. i.ibb.co/wzwQjkK/snapping-keys.gif $\endgroup$
