How to accept quests and broadcast clicks?

I only just got started 3 days ago? and i have no idea how to make it that quests are accepted on all characters. I am using keyclone and the only addon that i have so far is Jamba. Also if you could tell me how to broadcast the clicks (not sure if this is possible) instead of just when i hit the key it would be really appreciated.

You'll need some form of assist.

The easiest is a focus based approach.
If you're willing to work at it, the strongest is called an FTL Assist.

Anyway, for your question.
Target something with the main/active toon.
Press your assist key, so the slave/non-active windows now also have your target.

In warcraft options (mouse options), enable (check) click to move, probably better for all toons, but the slaves at least.
In warcraft keybinds (targeting functions), set a keybind for interact with target. In the case of both melee toons and non-melee, two keybinds is a good idea so you can IWT with everyone (quests, flight masters, inn keepers etc) and with only the melee (combat).

So you target with the main.
Press your assist, so the slaves get the master's target.
Press your IWT keybind.
Which will have everyone target the master's target and open the quest window.

At this point, anything you click with the active toon will have the slaves mimic your actions.
This works great when everyone is on the same stage of a quest.
But it is actually clicking the same option number.
So if they're on the same stage, then option 3 is option 3 for any of them.

In Jamba you can force each team member to take the same reward, to select their own rewards, to go with what the team picks (if they haven't picked one) but to go with their own choice if they have etc.
This setting will depend on what you want from the team.
An all shaman team might be happy to mimic reward choices, but a Paladin, Priest, Mage, Rogue, Hunter team will want different choices per toon.

I managed to do this thanks to you but just one more question please? :p

How do i make it so that i can just have one large window like full screen but the otheres running in the background?

I tried just going to video mode > Full screen and it just made it so that it didnt broadcast my commands. How would i fix this?

With the Keyclone Maximizer, you can set how large you'd like each region to be.

I'd recommend the same aspect ratio, between the large main window and the smaller slave regions.
I believe KC now has a wizard, which will set up your window layout for you.

Is it possible so that the main screen takes up the whole screen and i dont see any of the others? because when i just set it as one none of the other windows open up.

Not really sure on Clone Keys.
For some reason I thought you were using Keyclone, but I just noticed the thread tag.

I am using keyclone isnt clonekeys and keyclone the same? lol

Clonekeys = The only Mac boxing option (that I am aware of).
Keyclone = One of several PC boxing options.

Even if you make the slave windows tiny, I'd recommend having all of the windows visible.
It lets you visually determine follow status, or if they're stuck on something.
And then you can swap from one window to the next, via PiP swap.
