Make a Macro that is named "AoE" and type in /aoe as the only command. This allows you to toggle your spells to hit multiple targets (Area of Effect). Works with Cure as well!
Test it out. It will tell you that you are targeting Mutiple Targets, and then hit it again to toggle back to Single Target.
I have my class changing macros written like this.
/equip "Weathered Cane"
/eaction 2 "Thunder" main
/eaction 3 "Fire" main
/eaction 4 "Tranquility" main
/eaction 5 "Cure" main
In some cases you need to add the word "main" to the end of each /eaction to tell it what hand does the ability. For some classes this is not necessary.
/equip main "Weathered Fishing Rod"
/equip sub "Bronze Gig"
/equip pack "Bloodworm"
/eaction 2 "Wrist Flick"
/eaction 3 "Gulleye" sub
Notice you have to use the word "sub" for your off-hand, "pack" for arrows or bait.
DoL: Take a look at which of your Class's tools has a higher "scanning" ability on the equipment screen. Make sure to set your scanning ability (Gulleye, Lay of the Land, etc.) to that hand, usually the sub.
