I have searched a bit and haven't found out what to do. I have included modifiers in macros and would like to continue father that creating a separate hotkey for the modified command. For instance:

One part of my destro lock's dps step macro is this:

/castsequence [mod:shift] Soul Fire,; reset=target Immolate,Incinerate,Incinerate,Incinerate,Incinera te
/use 13
/use 14
/cast Demon Soul
/stopmacro [exists,harm,nodead]
/assist party1

Spamming this key (7) gets me the cast sequence but when add shift (shift-7) nothing fires. The above macro works like a charm when I use it without ISBoxer assistance. Is this because ISBoxer uses shift for other things? I want to be able to fire off Soul Fire when the instant cast procs. how can I make this work?

Thanks in advance.
