All blocks are called using tags {blocks}.

How can I display the individual blocks? I know they have their ID's, but I can't find anywhere in documentation how a tag invoking the individual block looks like? How to get some block's unique ID?

Additionally, is there any documentation on the list of Drupal's tags?

Guys, I am sorry - I am the Drupal beginner, and some things are very unclear to me even after fiddling with Drupal for a few weeks... :( Please, give me a hand here...
