I'm hoping someone more experienced then me can help me untangle how something works. I know that whenever two effects trigger at the same time then the person who controls the battlefield decides the order they trigger in. How does this apply when one of those effects causes another effect to trigger? For example:

Poe Dameron is equipped with Fast Hands and activates.

His opponent, who controls the battlefield, has Jango Fett equipped with Fast Hands as well.

He stacks the triggers so Jango resolves first. This trigger's Jango's fast hands. How is this Fast Hands trigger resolved? Before or after Poe's?

And to take the question a step further, say Jango also has Now I am the Master equipped as well, and he rolls a damage. Could his Fast Hands then add another trigger to the stack?

I'm just mystified about how this would work. Any help is appreciated!

Controlling the battlefield doesn't really play a role here. Jango interrupts and rolls in then Poe gets to use his fast hands then Jango gets to use his only because it's Poe's turn and he picks order with simultaneous actions. It's under simultaneous abilities on page 18 of the rulebook

The player who controls the battlefield decides in which order simultaneous effects controlled by different players enter the queue.

Non simultaneous effects enter the queue as they trigger.

So, in your example, Poe activates, his oponent decides to trigger Jango first, and Poe's fast hands enter right after Jango. Then Jango activates and his fast hands enter behind Poe's. Poe resolves a die, then Jango resolves a die, and NIATM enters the queue (and resolves, since there is nothing more to resolve).

Thank you!

For completeness of detail:

Poe activates and rolls. This triggers both Fast Hands (P) and Jango.
Battlefield controller chooses the order to enqueue. He picks Jango first, then Fast Hands (P).
Queue: Jango, Fast Hands (P)
Resolve next ability: Jango decides to activate, and rolls. This triggers Fast Hands (J).
Queue: Fast Hands (P), Fast Hands (J)
Resolve next effect: Fast Hands (P). Poe chooses a die and resolves it.
Queue: Fast Hands (J)
Resolve next effect: Fast Hands (J). Jango chooses a die and resolves it, dealing damage. NIATM triggers.
Queue: NIATM.
Resolve next effect: NIATM.
Queue: Empty. Move to next action.

The important thing to remember is that there's only one queue. You can put any new effects at the end of the line, and you always pull the next one off the head once the current is compete.

There's only one ability/effect queue. There's sort of 2 queues since additional actions exist outside of the ability/effect queue and live in a queue all their own.

This is functionally true, but they're careful not to actually call it a queue. They actually say explicitly that actions DON'T go into the (a) queue. Abilities go in the queue, actions are taken in the order they are granted. Totally different things But I try to respect the terminology to avoid confusion.
