FTL Shaman DPS Macro?

I run a focusless, leaderless setup, and i've been trying to figure out a dps macro for my tri-box team. due to the 255 character limit, I think it would hard to fit it in without a mod that extends macro capacity..anyone know a good stand alone mod that does ONLY that?

And

would a dps macro work with all the keymapping that happens with a FTL setup?

My typical macro starts out as follows

/target [mod:ctrl,mod:shift,nomod:alt,target=Trisham][mod:ctrl,mod:alt,nomod:shift,target=Triisham][mod:alt,mod:shift,nomod:ctrl,target=Trissham]
/cast [target=targettarget,harm] insertdpscasthere

Why dont you use /click to extend your macros? Requires no addons.

i.e.
Main macro:
/FTL targetting
/click ActionBarbutton 1
/click ActionBarButton 2

etc.

(obviously the syntax isnt right)
