Not sure I get what it is you're asking. No matter which record a user clicks in, it becomes the active/selected record. In other words, the active record is whichever record is current, no matter when you investigate that. However, maybe what you want is to use either exit, enter or gotFocus for one or more of the controls involved in the records.
Current event will fire when user selects a different record but not when moving from control to control on the same record. Not sure if that or this will help
