Ok, now comes the real hassle, by implementing the ftl-approach with hkn.
Here i have to coose a little between 'beauty' and 'function' as your need of a 5box viable and raid-viable setup gets it realy complicated if you can't life with HKN throwing errors
So the following is mainly for raiding, should also function for 5 boxing, but would throw some errors, because some windows are missing.

To get the ftl running in HotKeyNet do the following:

1. Define a modifier order (in general)

As allways with an ftl the first step is defining a modifier order associated with your toons to define who is leading.
You are lucky that you are using exactly 7 toons, as this is the magic number which can be addressed by using right alt,ctrl,shift.
(If it would be more, one of the left modifiers would be needed)

For the following I suggest this order:

Coltimar = ralt
Marlun = rctl
Jermayne = rshift
Teetoe = ralt + rshift
Jackea = ralt + rctrl
Coventar = rshift + rctrl
Faxindaxis = ralt + rctrl + rshift

2. Define the Modifier-order in HKN

the order defined in 1. now must be translated in HotKeyNet-Code to achive the following, when a 'master-key' is pressed:
(for definition of master and slave-key see: ftl-wiki )
- The active-window recieves the 'master-key'
- All not active windows recieve the mofifier-order which is associated with the active window plus the 'slave-key'

Or as a simple example with Jermayne as the active window and '1' as the master-key, 'u' as the slave key:
(Btw. I often use the same key for master/salve-key, but to give the general idea here an example with different keys)
If '1' is pressed on Jermayne:
- Jermayne recieves '1'
- All other Windows revieve: 'rshift + u'

This logic can be achieved with HKN by the following code:
Code:
<command JermayneMaster>
	<SendPC Local>
		<SendWin Jermayne> 
			<Key %all%>
			
<command JermayneSlave>
	<SendPC Local>
		<SendWinM Coltimar> 
			<Key rshift %all%>
		<SendWinM Marlun> 
 			<Key rshift %all%>		
		<SendWinM Teetoe> 
 			<Key rshift %all%>
		<SendWinM Jackea> 
 		 	<Key rshift %all%>
	<SendWinM Coventar> 
 		 	<Key rshift %all%>
	<SendWinM Faxindaxis> 
 		 	<Key rshift %all%>

<Hotkey 1>
<If ActiveWinIs Jermayne> <JermayneMaster %trigger%><JermayneSlave u>
of course you don't only want to be able to use Jermayne as the active window, so you would define the corresponfing commands fpr the other toons to, looking like this:

Code:
<command ColtimarMaster>
	<SendPC Local>
		<SendWin Coltimar> 
			<Key %all%>
			
<command ColtimarSlave>
	<SendPC Local>
	  <SendWinM Jermayne> 
			<Key ralt %all%>		
		<SendWinM Marlun> 
 			<Key ralt %all%>		
		<SendWinM Teetoe> 
 			<Key ralt %all%>
		<SendWinM Jackea> 
 		 	<Key ralt %all%>
	<SendWinM Coventar> 
 		 	<Key ralt %all%>
	<SendWinM Faxindaxis> 
 		 	<Key ralt %all%>

<command MarlunMaster>
	<SendPC Local>
		<SendWin Marlun> 
			<Key %all%>
			
<command MarlunSlave>
	<SendPC Local>
	  <SendWinM Jermayne> 
			<Key rctrl %all%>
		<SendWinM Coltimar> 
			<Key rctrl %all%>		
		<SendWinM Teetoe> 
 			<Key rctrl %all%>
		<SendWinM Jackea> 
 		 	<Key rctrl %all%>
	<SendWinM Coventar> 
 		 	<Key rctrl %all%>
	<SendWinM Faxindaxis> 
 		 	<Key rctrl %all%>

<command JermayneMaster>
	<SendPC Local>

	<SendPC Local>	 
		<SendWinM Coltimar> 
			<Key rshift %all%>
		<SendWinM Marlun> 
 			<Key rshift %all%>		
		<SendWinM Teetoe> 
 			<Key rshift %all%>
		<SendWinM Jackea> 
 		 	<Key rshift %all%>
	<SendWinM Coventar> 
 		 	<Key rshift %all%>
	<SendWinM Faxindaxis> 
 		 	<Key rshift %all%>
 		 	
<command TeetoeMaster>
	<SendPC Local>
		<SendWin Teetoe> 
			<Key %all%>
			
<command TeetoeSlave>
	<SendPC Local>
	  <SendWinM Jermayne> 
			<Key ralt rshift %all%>
		<SendWinM Coltimar>

 		 	<Key ralt rshift %all%>
	<SendWinM Coventar> 
 		 	<Key ralt rshift %all%>
	<SendWinM Faxindaxis> 
 		 	<Key ralt rshift %all%>

<command JackeaMaster>
	<SendPC Local>
		<SendWin Jackea> 
			<Key %all%>
			
<command JackeaSlave>
	<SendPC Local>
	  <SendWinM Jermayne> 
			<Key ralt rctrl %all%>
		<SendWinM Coltimar> 
			<Key ralt rctrl %all%>
		<SendWinM Marlun> 
 			<Key ralt rctrl %all%>		
		<SendWinM Teetoe> 
 			<Key ralt rctrl %all%>		
	<SendWinM Coventar> 
 		 	<Key ralt rctrl %all%>
	<SendWinM Faxindaxis> 
 		 	<Key ralt rctrl %all%>
                                         		 	
<command CoventarMaster>
	<SendPC Local>
		<SendWin Coventar> 
			<Key %all%>
			
<command CoventarSlave>
	<SendPC Local>
	  <SendWinM Jermayne> 
			<Key rshift rctrl %all%>
		<SendWinM Coltimar> 
			<Key rshift rctrl %all%>
		<SendWinM Marlun> 
 			<Key rshift rctrl %all%>		
		<SendWinM Teetoe> 
 			<Key rshift rctrl %all%>
		<SendWinM Jackea> 
 		 	<Key rshift rctrl %all%>	
	<SendWinM Faxindaxis> 
 		 	<Key rshift rctrl %all%>
 		 	
<command FaxindaxisMaster>
	<SendPC Local>
		<SendWin Faxindaxis> 
			<Key %all%>
			
<command FaxindaxisSlave>
	<SendPC Local>
	  <SendWinM Jermayne> 
			<Key rshift rctrl ralt %all%>
		<SendWinM Coltimar> 
			<Key rshift rctrl ralt %all%>
		<SendWinM Marlun> 
 			<Key rshift rctrl ralt %all%>		
		<SendWinM Teetoe> 
 			<Key rshift rctrl ralt %all%>
		<SendWinM Jackea> 
 		 	<Key rshift rctrl ralt %all%>	
	<SendWinM Coventar> 
 		 	<Key rshift rctrl ralt %all%>
the above described FTL-Key can then be defined like:
Code:
<Hotkey 1>
<If ActiveWinIs Coltimar> <ColtimarMaster %trigger%><ColtimarSlave u>
<Else If ActiveWinIs Marlun> <MarlunMaster %trigger%><MarlunSlave u>
<Else If ActiveWinIs Jermayne> <JermayneMaster %trigger%><JermayneSlave u>
<Else If ActiveWinIs Teetoe> <TeetoeMaster %trigger%><TeetoeSlave u>
<Else If ActiveWinIs Jackea> <JackeaMaster %trigger%><JackeaSlave u>
<Else If ActiveWinIs Coventar> <CoventarMaster %trigger%><CoventarSlave u>
<Else If ActiveWinIs Faxindaxis> <FaxindaxisMaster %trigger%><FaxindaxisSlave u>
