How to display SQL queries used?

I know you can make these {command} by yourself and CodeIgniter already has the elapsed time command. But how can I display the number of SQL queries used?

Code:

echo $this->db->query_count;

Use the Profiler class

Thanks a lot.

Edit: Waow, that's a pretty neat feature, Colin! I didn't know you could do it like that.
