The act of Scripting is using a third party program-typically to predict human behavior-in order to place an unfair advantage in the players hands. Sometimes it's really hard to tell a Scripter from an extremely skilled player because at times it almost seems like they predict your actions-both dodging them and making skillshots that seem impossible to dodge. Sometimes someone is playing particularly well, but Scripting is something else all-together.
In your case, you simply remapped hotkeys. Considering this is a legitimate part of the game and doesn't affect gameplay to place an unfair advantage at your disposal, it's perfectly fine and you have nothing to worry about.
