(jamba) FTL

im using jamba and im thinking of ding dualboxing in bg but then i want FTL to work and to be honest i try to understand how it works but i still dont get it i have read on forums how to use it but i cont understand.
can some one tell it to me simpel and proper my and dos it mean i can have my 2 toon as master is my normal master dies?

is it posible to change the FTL button to like F1,F2,F3. etc.... ?

i am new in dual boxing atm im seting up a F2P dualboxing but i wana make sure i know what im doing before i start propperly, and i using the program Octopus_1.3.8

dos this mean i can have one of my alts as "master" for a wile til my master come back? like in /assist master nomather witch toon it is ?

thanks

Make the following macro on all toons:

/jamba setmeasmaster all

Switch to the toon you want to become master and click that macro.

so when my master die and im on a slave i just press that one and thats the master after that?
and how do i make the toons to attack the same target without using /assist (main name) ?
