Add Keys stays active until you activate a different tool. If you add a key in a component of a multi-part controller, vertices are inserted to each curve at the time location where you clicked. For example, adding a key to the red X curve of a TCB Position track simultaneously inserts keys in the green Y curve and the blue Z curve. Tip: You can move a new or existing key while in Add Keys mode simply by dragging it. In Dope Sheet and Curve Editor modes, you can change the timing by dragging the key horizontally. In Curve Editor mode, you can also change the value by dragging the key vertically. The value of each added key is set by one of the following conditions: . Keys added between keys receive the interpolated value at that location. Keys added before the first or after the last key receive the same value as the nearest key. You can change a key value and/or time while adding it by dragging after clicking the curve. To add keys to a function curve:. In the Hierarchy list, highlight a track. On the toolbar, click Add Keys. To add keys in Dope Sheet mode:. On the toolbar, click Add Keys. Keys added before the first key of a track receive the same value as the former first key.
