SQL*PLUS

I have a question about Oracle SQL*PLUS. I know that "SELECT * FROM TAB" can display all the table names and "SELECT * FROM SEQ" can display all the sequences. The question is, if I want to display all the triggers, what command do I use?
I appreciate if any guru can help.

This command will give you the trigger names

select trigger_name from user_triggers

All the best.
