Add Keys (Function Curves)

Add Keys is a mode that stays active until you click another mode. While Add Keys is active you click anywhere on a function curve to add a key at that location on the curve.

If the selected curve is part of a multi-curve controller, vertices are added to each curve at the time location where you clicked. For example, adding a key to the red X curve of a position track will also add keys at the same time to the green Y curve and the blue Z curve.

Adding keys to a multi-curve controller

The value of each key is set by one of the following conditions:

• Keys added between keys receive the interpolated value shown by the function curve at that location.
• Keys added before the first or after the last key on the curve receive the same value as the nearest key.

Another way to add keys is to copy them using one of the transform buttons with Shift-Clone.
