You can also have Clique use the macros you've created within the game either under your global macros panel or your character customize macros panel.
Global macros use Macro Index 1-36
Character Specific macros starts at Macro Index 37-73
I was playing with this yesterday, and if you write a new macro, WoW's system will sort the macros alphabetically by name, so I appended 0# to all my macros to preserver order (where # is a wildcard number).
If for some reason you also use target healing as well, you can change Sionnaine's [target=mouseover] to
/cast [target=mouseover,exist]  <spell name>
that way it will work if you use Clique's clicking, or if you don't wanna mouseover anyone, and wanna cast the spell on your current target.
