How to change leader on the fly.

I'm new to multiboxing here, so bear with me. I need to know how to change the leader of my group on the fly in case one dies or to confuse players when it comes to PvP. I have read up on FTL, but it seems a little complicated to set up for me. If there is another way on how to set this up, or someone could clarify on FTL, I would be greatly appreciative.

~~~About my Setup~~~
Program- Keyclone
Game- WoW
Team Members- Five Hunters (Heliasus, Heliesus, Heliisus, Heliusus, Heliysus)
Computers- One: (Intel Core i7, 8G of ram, Nvidia 560m 1.5GB video card)

You can try a focus based setup. Just set all of your toons to assist focus, and set the toon you are driving with as focus.

Get a trial of IS Boxer.
That's seven days to try it out.

The wizard will generate a number of mapped keys for you.
1, 2, 3, 4, 5, 6, 7, 8, 9, 0, -, and = will all be FTL DPS Keys.
Meaning, from any window, press that key and they all will press whatever is on the keybind, but assist the active window first.

FTL stands for assisting that is not based on Focus, Target or Leader.
You can set that up with Keyclone, via Hotstrings, but the process is rather complicated.

IS Boxer does FTL for you.
It has instant window swaps between toons.
It has accurate mouse broadcasting in real time.

There are two "broadcast" modes.
Broadcasting (the Keyclone term) is the same as Repeater (the IS Boxer term).
IS Boxer also has mapped keys, which are keys with hotkeys that do whatever.
You can have both on, both off, or either on and the other off.
It's a little different from Keyclone, but far more powerful.

If both Keymaps and Repeater are on, Keymaps have priority.
You'd want Keymaps on, and Repeater off for 99% of your in-game play.
Repeater on, and Keymaps off, for entering your passwords or for everyone to /dance or type /macro in game.
Both on, to briefly click something with the mouse.
Both off, to chat with a single toon either via whisper or /bg /raid chat.

I have and idea for the focus-based system. What if I have it so the keys "Page Up", "Page Down", "Home", "End", and "-" all correspond to have it so when I press "Page Up", for example, they all focus on one character, in this case for "Page Up" they all focus on Heliasus. This would be macro based, with the setup like this:

/focus "InsertCharacterName"

Each key is set to focus on a different character, and when I need to change characters, I just press the key I need to press and switch windows, then apply my follow macro (based off focus) and the leader changes just like that. I had some problems setting this up though, as when I tested the macro, the character wouldn't focus. I'm not sure if this is a limitation within game or keyclone, or maybe something on my part. If someone could clear this up for me, that'd be great.

~~~EDIT~~~
I think my problem might be the macro itself. Instead of the one listed above, I might need:

/target "InsertCharacterName"
/focus target

Any and all feedback is greatly appreciated :)

Do what Ualaa said, ISBoxer makes FTL very simple indeed.

Isboxer is easiest by far. Before Isboxer I used keyclones PiP functionality and setup 5 keys (I used F1-F5). Then I used these macros...each toon needs 1 leader macro and 4 alt macros plus the follow macro

Leader
/focus leader (toons name)
/script SetBinding("W", "MOVEFORWARD")
/script SetBinding("A", "TURNLEFT")
/script SetBinding("S", "MOVEBACKWARD")
/script SetBinding("D", "TURNRIGHT")
/script SaveBindings(1)
/jamba-follow strobeonme all
/console autointeract 0


Alts
/focus leader (alt names)
/script SetBinding("W", "MACRO Follow")
/script SetBinding("A", "MACRO Follow")
/script SetBinding("S", "MACRO Follow")
/script SetBinding("D", "MACRO Follow")
/script SaveBindings(1)
/console autointeract 1

Follow
/target focus
/follow
/cleartarget

I agree the simplest way is e.g. F1 has window swap AND focus switch AND jamba master switch for toon 1 . Then any dps macros on slaves start with /assist focus. Repeat on all toons.

Okay, so here's what I did:

I completely dropped the idea of using FTL at all. I only needed a way to switch leaders quickly and I found it best to just use macros. I did what I described above, Using the keys "Page Up", "Page Down", "Home", "End", and "-". Each key was assigned to focus on one character, and when pressed, all characters (minus the one that I wanted to be leader) would target and focus on the character I wanted to make as leader of the group. I then switch windows to my new leader, press my follow macro, and continue on as normal. This works perfectly for me, as its not an overly complicated setup. The macro I used is as follows:

/target "InsertCharacterName"
/focus target

/click ISBoxer free trial (7 days)

/be happy
/dance

ISBoxer FTL is easy as pie. And it tastes good too:)

I am sure there are other ways but this Is just my 2 cents.
