/run local x = IsShiftKeyDown(); if x == nil then CastSpellByName("Seal of Command(Rank 3)") else CastSpellByName("Seal of Command(Rank 1)"); end;


Is it possible to make this macro workable?

You forgot a semi-colon after Seal of Command r3.
/run local x = IsShiftKeyDown;if(x == nil) then CastSpellByName("Seal of Command(Rank 3)"); else CastSpellByName("Seal of Command(Rank 1)");end;

Those shouldnt be required^^

Try this:

/run if (IsShiftKeyDown()) then CastSpellByName("Seal of Command(Rank 1)") else CastSpellByName("Seal of Command(Rank 3)") end

That should work
