Find the term_ids for tags

I’m trying to figure out how and where to find the term_ids for tags so that I can use the following function:

<?php wp_tag_cloud(‘smallest=8&largest=22&number=30&orderby=count&include=???’); ?>

The issue comes in knowing the term ids to include for tags, which also would come in handy for creating custom tag-13.php templates, for example.

Finding the ids for categories, users, etc… is as easy as looking in the admin, but where would I go about finding them for tags?
