Hi,

the difference is basicly in the 'concept' of an ftl, and as a conclusion of that both in the macros and in HKN.

The general concept of an FTL is, that the 'leader' is not specifiyed by 'focus' or 'target', but implicit simply by which window you actualy play in. So if one char is dead, you simply can switch over to another window an play from there, without the need of setting a new focus..

This is achieved by the following:

1. Each window is associated with a modifier-combination, which identifiys it.
2. When you press an FTL-Key (lets say 2), the active window simply recieves the '2' but for all other widows, the modifier-combination for the active window (like f.ex. 'rshift + ralt') is also transmitted (so all 'slave'-windows get 'rshift + ralt + 2') (This is the part you set up in HKN with the above Templates)

To get all Toons in WoW to 'assist' (or follow) you current master (which is allways the one which window is active) you create a 'assist' and 'follow' macro like this:

lets say your Toons are idetifyed with the following modifiers:

rCtrl + rShift = ToonA is leader
rCtrl + rAlt = ToonB is leader
rAlt + rShift = ToonC is leader
rCtrl + rAlt + rShift = ToonD is leader
rCtrl = ToonE is leader

So you would use this macro for follow:
Code:
/stopmacro [nomod]
/target [mod:rctrl,mod:rshift,nomod:ralt,target=ToonA][mod:rctrl,mod:ralt,nomod:rshift,target=ToonB][mod:ralt,mod:rshift,nomod:rctrl,target=ToonC][mod:rctrl,mod:ralt,mod:rshift,target=ToonD][mod:rctrl,nomod:ralt,nomod:rshift,target=ToonE] 
/follow 
/targetlasttarget
and this macro for assist:
Code:
/stopmacro [nomod]
/assist [mod:rctrl,mod:rshift,nomod:ralt]ToonA;[mod:rctrl,mod:ralt,nomod:rshift]ToonB;[mod:ralt,mod:rshift,nomod:rctrl]ToonC;[mod:rctrl,mod:ralt,mod:rshift]ToonD;[mod:rctrl,nomod:ralt,nomod:rshift]ToonE
You see, in both macros the individual modifier combinations for the Toons (like rctrl for ToonE) are 'questioned' and if present, the corresponding toon is assited or followed.

To make this work in WoW you bind the follow and assist macro to a specific key (lets say 1= follow, 2=assist) and you need to make sure, that all shift/alt/ctrl-combinations are unbound in the wow interface. For simplification you need to remember which Button you draged the 'assist'-macro to (for the example I will assume that you used the secondposition on the normal 'main'-bar of wow (ActionButton2)).

In HKN, you use the Templates above, and simply define a new FTL-Key like

<ApplyTemplate FTL "1" "1">
<ApplyTemplate FTL "2" "2">
(and customize the Windownames, labels etc, if you use other tahn me).

Now what you do for all your ftl-casts is the following:
1. define them as an FTL-Key in HKN
2. Create A macro for your cast like you would normaly, and add a '/click ActionButton2' at the beginning and a '/targetlasttarget' at the end
3. Drag the Macro to the button you want to bind it to
4. make sure, that alt/ctrl/shift is unbound for that button.

Example: Lets say we want to cast Lightning Bolt with pressing '3':

Step 1: We add <ApplyTemplate FTL "3" "3"> in the HKN-File
Step2 : We create the following macro:
Code:
/click ActionButton2
/cast Lightning Bolt
/targetlasttarget
Step3: We drag the macro to the 3rd button of the actionbar
Step4: We go to the keybindings menu and check that alt/ctrl/shift + 3 are unbound...

I hope the main functionaloty of an ftl gets a little bit clearer, for more information on this you could also read the wiki/sticky about it.
