TraceAbove
 Usage
• TraceAbove is an option for Trace and related functions which specifies whether to include evaluation chains which contain the evaluation chain containing the pattern form sought.
Notes
• TraceAbove -> True includes the first and last expressions in all evaluation chains within which the evaluation chain containing form occurs. • TraceAbove -> All includes all expressions in these evaluation chains. • TraceAbove -> {backward, forward} allows you to specify separately which expressions to include in the backward and forward directions. • Using TraceAbove, you can see the complete paths by which expressions matching form arose during an evaluation. • New in Version 2.
