Absolute: Current values in the active list or animation layer.
Offset: Always reads the value of 0,0,0 and can be used to offset the absolute value by any given amount.
Keying: Will set keys or reset the values to 0,0,0 for the currently active controller or layer for the current transform mode only.
Works with mulitple selected objects. If the values of all the selected objects are not the same the Absolute value fields will be blank. If all the values are the same it will show the current value. This doesn't require that the same controller in a list or animation layer be active. It will always show the values for the currently active controllers.
