Mod Conditionals within macros don't work. e.g.

/cast [mod] schism
/cast smite

In this example 'schism' wont cast.

That makes sense, it will only listen for the exact keybind that you assign to it, so assigning Q to a binding won't cause SHIFT-Q to activate that binding, even if there is no explicit keybind for SHIFT-Q.

Really the only way to fix it using Clicked is by creating two bindings, one for Schism, and one for Smite.
