LiveBindings actions are new in XE3. If you are not familiar with actions, follow this link. LiveBindings actions correspond to the buttons on the TBindNavigator such as First, Next, Edit, Post, and Delete.
Steps for creating a speed button which uses a LiveBindings action:
Drop a TPrototypeBindSource on the form and add fields. See this post.
Drop a TActionList
Drop a TSpeedButton
In the object inspector, click the down arrow next to the SpeedButton1.Action property.
