For example, you can have two slots named "Cube" in an action as long as one of them is for objects and the other is for materials, but not if they are both for objects.  When they are both for objects, their associated type is the same, and thus they must have different names.  In that case Blender will use the familiar approach and name them "Cube" and "Cube.001".

+In addition to letting Blender automatically choose an action and slot for a data-block, you can also manually assign them.  This can be used to assign existing animation to a data-block by selecting both the action and slot.  It can also be used to specify an action for a data-block's keys to go into, by assigning the action but leaving the slot blank, in which case a new slot will be created when the first key is set.
 
 For each data-block in the properties editor there is an Animation panel with action and slot selectors.  You can use these to assign actions and slots to a data-block.

    When selecting a slot for a data-block, you won't necessarily see all the slots of an action listed in the dropdown.  This is because Blender limits that dropdown to the slots with an associated type that matches the data-block.
 
-When you select an action to animate a data-block, for convenience Blender will also attempt to automatically select an appropriate slot for you based on name and associated type.  If no appropriate slot is found then the slot selector will remain empty, in which case you can manually select an existing slot, create a new one, or just start keying and let Blender automatically create a new slot for you.
