Give the current Action a new and unique name. After the new name is entered, it appears in the list, sorted alphabetically.


If this button is displayed, there is more than one user for the Action block. Use the button to make the Action "Single User".

Unlink Action

The current Action is unlinked.


Generate an action based of the current action where the constraints effects are converted into IPO Keys.


This buton locks the update of the 3DWindow while editing in the ActionWindow, so you can see changes maked to the Action in realtime in the 3DWindow.


The ActionWindow gives an overview of the current Armature Keys and Relative Vertex Keys of the Object. It presents the time, in frames, on an horizontal axis and, vertically, as many stripes are there are bones in the armature or Relative Vertex Keys.

If the object is an armature bone Keys are represented as grey rectangle at the pertinent frame, yellow if selected. If it is a Mesh, Rectangles are present where a Key is assigned a given value. THis can be assigned via IPO or via the sliders in the ActionWindow.
