# Animating Keyframes

You can build animations simply by editing the values of parameters in any effect editor or menu. When you animate a parameter, you create an animation channel that you can use to control the values of the parameter over time.

To use auto key to build animations automatically in the editor for an effect or tool:

1. Enable Auto Key.
2. Go to the frame where you want to add the keyframe.
3. Change the value of the parameter. Enter a new value in the field using the calculator, or click and drag left or right to change the value.

   A keyframe is added to the animation channel for the parameter you edited.

   NoteWhen auto key is enabled, you create keyframes whenever you change the value for a parameter. You also change the value of any parameter that you have already set.

To set keyframes manually in the editor for an effect or tool:

1. Disable Auto Key.
2. Go to the frame where you want to add the keyframe.
3. Change the value of the property. Enter a new value in the field using the calculator, or click and drag left or right to change the value.
4. Right-click the field and select Set Keyframe (Current Value).

To delete keyframes:

1. Go to the frame that contains the keyframe you want to delete.
2. Right-click the parameter that contains the keyframe and select Delete Keyframe.
   NoteA yellow bar appears under values that are keyframed at the current frame.

To reset keyframe values:

1. Right-click the parameter and select one of the following options.

   Select: | To:
   --- | ---
   Reset (Default Value) | Reset the value of the keyframe to the original value.
   Reset Channel (Current Value) | Reset the value of the entire channel to the current value.
   Reset Channel (Default Value) | Reset the entire channel to the original value.
