I tried multiple ways and I don’t think it is the macro that is at fault. Simply because lots of other macros that I have do work. I can only speak of Era though, might be different macro behaviour over there?
I use shift+T for the summon and want to use ctrl as mod to teleport. I also tried binding it to T but my ctrl keys don’t seem to have a function in macros. Only shift works. For me personally it looks like ctrl is blocked by the pet bar.
Select the ? for the macro icon and see if the icon changes when it should. If it does but pressing the key combo doesn’t fire the spell then you have a keybind conflict and the conflict will need to be unbound. The pet bar isn’t special aside from being bound to CTRL 1-6 by default.
