Are Macros Allowed? If So, Could Someone Please Help Me?

I just want to ask, are macros allowed? I'm getting really tired of trying to cast Ice snake and Meteor but instead casting Ice snake-Ice snake or Heal and Ice snake.
If they are allowed, can someone help me get them? I really want to actually do some good combos (Such as Ice snake, TP, then meteor).

 

It's fine if they are not in a loop.

 

Macros are allowed if you use it in a way that you push 1 button and it casts 1 spell. No looping or anything like that.

Yet, I wouldn't suggest it. I tried a spell macro mod once.
-Weird string system; sometimes the code doesn't work
-Got a consistent 4 fps the entire time I was using it
-80% of the time it activated the wrong spell
-It's inconvenient to reach specific keys to activate spells when you could just R-L
etc

 

Welp, luckily I got these Macrokeys on my mouse :3

 

I once tried macros, but sadly the game (server) had trouble registering mouse buttons, and instead of doing RLR it sometimes did only RL or evev RR
