How to delete a track in sequence X6

I searched everywhere for how to delete a track in Sequence mode and cannot find it? Not in the users guide or online or I'm stupid after 20 years. I know how to delete one track while working on it to do live while sequencing, but how to delete or "mod" say a drum track that is not working? Maybe it was the 3rd track I recorded and is not happening anymore and would like to delete or re-record that track/punch in maybe? 3 months and cannot figure out how to "skip back" to a prior track with new ideas. Thanks!
