What is the TX key?

What is the TX key? I know it is related to $r$ from the whitepaper, but I'm not sure which number it is. (I'm thinking it is either r, rA, or H(rA)).

Simplewallet: How do I get the tx_id needed for check_tx_key and get_tx_key?

I tried to use the transaction hash, but that seems to be something different than tx_id. For example with this: get_tx_key I got an error "no tx key found for this txid".

Why do I see only one transaction key R=rG per transaction while there are multiple output keys P=H(rA)G+B to represent multiple denominations?

As I understand from the whitepaper, the sender picks random r to create one-time output public key P=H(rA)G+B, and the public transaction key R=rG is attached to the transaction data. Since any amount sent to the receiver needs to be split into…

How to identify sender when they send monero?

My current understanding is that when I expect to receive monero from many people, I send each subaddress to each one of them to identify which one sent how much. But it seems to be troublesome for me to generate a lot of subaddresses. So I will…

Is it easily provable by a third party that the key image used in a transaction is associated with the spent output without revealing the (P,I) pair?

What I'm getting at is I'd like to know how the Monero network can know that a key image used in a transaction is not either forged (probably an easy answer) or created from a different output owned by the same wallet (perhaps a more technical, but…

Can the sender find an address of the receiver of the transaction when not using GUI wallet?

wallet-CLI was used to send the transaction, but the sender forgot, where he send the money, so is there a way to determine, where it was sent? I would prefer wallet-CLI or wallet-RPC solution if there is any.
