FTL With Multiple Chars/Account No Addons Needed

[thebunch]

/introduction and thanks
Hi guys, first I want to say that I’m german and my English became a little rusty since school, so please excuse my errors and correct me pls when I write total bullshit ;).
I want to start multiboxing in the near future and read this forum some weeks now, I have no installed wow atm, because im learning for my university tryouts, so all i do is think about my configuration, without the possibility to test it ;) (i love to configurate somethink).
I want to 5box on 1 pc, with hotkeynet and jamba. Olipcs explaination of the ftl setup makes it so attractive ;), thank you man, you are the “most helpfull person of the year” (© frosty) indeed!!!
I must say here are some very helpful people and the community is very nice, the spike of the better wow people ;).
/blabla end ;)

My question:

Can I use ralt, rshift, rctrl in my ftl targeting macro

/target [mod: rshift, nomod: rctrl/ralt, target=A]
[mod: rctrl, nomod: rshift/ralt, target=B]
[mod: ralt, nomod: rshift/rctrl, target=C]
[mod: rshift rctrl, nomod: ralt, target=D]
[mod: rshift ralt, nomod: rctrl, target=E]

And modifiers lshift, lctrl, lalt in the spell macros

/click targeting macro
/assist
/cast [mod: lshift, nomod: lctrl lalt] pewpew
/cast bangbang
/targetlasttarget

(modified with spaces for better readability)

will this work, or is there another solution to use modifiers with ftl macros? i didnt find anything with the search function ;(.

UPDATE
ok, fuck i installed wow. so no learning today anymore ;). i testet the 2 macros in shorter form on an lvl 1 char. it works!

target macro:

/target [mod:rshift,nomod:rctrl/ralt,target=player];
[mod:rctrl,nomod:rshift/ralt,target=ruk warstomper]

skill

#show
/click ActionButton2
/cast [mod:lshift]Healing Wave;[nomod:rshift/rctrl]War Stomp

without any mod, i just warstomped, with either rshift rctrl pressed it targeted the right, with lshift and rshift pressed it healed me and with lshift and rctrl it healed ruk. i can switch between the two target while holding lshift. so i think it schould definitiv work with the ftl setup via hotkeynet, more precicly i hope so ;). can someone test it with more toons and hokeynet?


p.s. can someone recommend an english pvp realm [EUROPE] [H]? with multiboxer / ~ firendly guilds for some premade bgs and arena?
