nothing happened because there was no active program to debug.
suggest you either read the documentation or ask a co-worker or your support. This is education, you company should provide it.
also, the online help is rather extensive.
i can not remember the primary screen (1 or 2) but option 6 allows you make entries for programs/transactions that should be debugged.
in the event that it is a non-terminal transaction (e.g. web invoked) put all '*' in the terminal field, otherwise enter your terminal name in the field, else you will stop all transactions of same type.
