Talking macro, HELP!!

I want a macro that can say two different things with two different buttons, like the poison macro

#showtooltip

/use Deadly Poison VI

/use [button:1] 16; [button:2] 17

but that says different things, like "Hi m8!" on [button:1] and "Hello!" on [button:2]|||would this work?

/s [modifier:shift] hi m8; hello

I'm hoping that would say hello if you press the macro button and hi m8 if you press the macro button+shift

You can change the modifier to alt or control IIRC.
