Hey, for as long as I can remember I've been using Macros such as:

#showtooltip Flash Heal
/cast [target=mouseover,help][help][target=player] Flash Heal
and that works perfectly fine, where it heals people I mouse over... or myself when I've moused over nothing.

Would it be at all possible to combine this with a modifier to another spell ?

I tried:

#showtooltip
/cast [mod:shift][target=mouseover,help][help][target=player]Saving Grace; [target=mouseover,help][help][target=player]Prayer of Mending
But that doesn't work... even though I got Saving Grace modified the macro just cast sees Saving Grace and not PoM, and just casts SG whether I got shift held down or not.

Any help would be very much appreciated.

Nevermind, figured it out:

#showtooltip
/cast [@mouseover,help,mod:shift][@player,mod:shift]Saving Grace; [@mouseover,help][@Player]Prayer of Mending
