Enabling/Disabling Keyframes for Individual Channels

A keyframe is created each time you change a layer's channels when the Animate button is enabled. You can disable keyframing for individual channels that you do not want to animate. You can also disable keyframing to temporarily hide a channel's animation.

To enable or disable keyframing for a channel:

In the Timeline list, click the key next to the channel.

When the key is highlighted, keyframes are enabled. When the key is gray, the channel maintains a constant value (based on the last value you set).
