The Edit menu gives you tools for adjusting animation data and working with controllers.
Puts a copy of the selected controller track into the Track View buffer. See Copy Controller.
Copies the controller track in the Track View buffer onto the selected track of another object or objects. You have the option of pasting as a copy or as an instance. See Paste Controller.
This submenu provides tools for moving and scaling animation keys:
When on, keys always snap to frames. When off, you can move keys to sub-frame positions. See Snap Frames.
This submenu provides tools for working with animation controllers:
Assign Lets you assign the same controller to all highlighted tracks. See Assign Controller.
Delete Lets you delete certain controllers that can't otherwise be replaced (Visibility tracks, Image Motion Blur Multiplier, Object Motion Blur, On/Off). See Delete Controller.
Collapse Converts procedural animation tracks (such as Noise) to Bezier, Euler, Linear, or TCB keyframe controller tracks. Can also be used to convert any controller to these type of controllers. Allows for key reduction by using a Samples parameter. See Collapse Controller.
Keyable Toggles the ability of highlighted controller tracks to receive animation keys. To see whether a track is keyable, turn on Show Keyable Icons.
Enable Anim Layer Assigns a Layer controller to each highlighted track in the Controller window. See Animation Layers (Layer Controller).
Ignore Animation Range Ignores the animation range for the selected controller track. When set, the track plays independently of its range and its background changes color. See Ignore Animation Range.
Respect Animation Range Respects the animation range for the selected controller track. When set, the track plays only within its range. See Respect Animation Range.
Make Unique Lets you turn an instanced controller into a unique controller. If a controller is instanced, making changes to it will affect where ever it is copied. If the controller is unique, then changes to it will not affect anything else. See Make Controller Unique.
Out of Range Types Lets you extend the animation beyond the existing keyframes. Used primarily to loop and otherwise cycle your animation without having to copy keys. See Parameter Curve Out-of-Range Types.
Displays the Properties dialog, which gives access to the key interpolation types. Different controller types offer individual options here. For example, the Position XYZ controller offers Fast, Slow, Linear, Smooth, Step, Bezier and Auto Tangent as key options, while a TCB controller will not show any of those controls. For some controllers this is the primary gateway to the animation parameters. See Properties (Track View).
Lets you add or remove Note tracks to your scene. You can use Note tracks to add any sort of information to tracks in Track View. See Add Note Track and Remove Note Track.
Lets you add or remove Visibility tracks to objects your scene. You can also keyframe visibility by changing the Visibility parameter in the Object Properties dialog when Auto Key is on. See Add Visibility Track and Remove Visibility Track.
Opens a dialog that provides access to a number of useful tools. See Track View Utilities.
