Code:
#showtooltip
/cast [mod:shift] Spell 1; [mod:ctrl] Spell 2; [mod:alt] Spell 3; Spell 4
If SHIFT is pressed, cast Spell 1.
If CTRL is pressed, cast Spell 2.
If ALT is pressed, cast Spell 3.
If no modifier key is pressed, cast Spell 4.
You can remove ones you don't use, and if you want something to work on ANY modifier, you can do this:
Code:
#showtooltip
/cast [mod] Spell 1; Spell 2
If ALT, SHIFT, or CTRL is pressed, cast Spell 1.
If no modifier key is pressed, cast Spell 2.
