Pet macro help

i have this so far:
#showtooltip
/use [@pet,dead] Revive Pet; [nopet] Call Pet 1; Mend Pet
I would like to add a modifier so that if I use ALT I cast Exhilaration instead.

Thank you in advance.

[mod:alt] exhilaration
Slot it in depending on when you want it to cast. If you wanted it to only cast while you had a pet out for example:

#showtooltip
/use [@pet,dead] Revive Pet; [nopet] Call Pet 1; [mod:alt] exhilaration; Mend Pet

If you always want it to cast, put it at the very front
