how to use Blockchain.org to investigate addresses and transactions

[Bittery]

I have been using BTC for a few weeks now and know how to put a public key into blockchain.org´s search bar to check on the balance and history of each key.
What I´d like to learn more about is the transactions part of the page.
What are the different elements and links on the page? and how to use them?

many thanks
