Just be careful about using this.
1. It is illegal because it breaks copyright according to the DMCA
2. It is a breach of Jagex's ToS, so if they find out you're using it, they have the right to ban you, even if you're playing 100% legit on it.
3. Autotypers are very quickly being auto-perm muted lately with Jagex's BotWatch system
4. An autoclicker like that would be very very easy for Jagex to detect, so I'd avoid using it on an account you don't want banned
Those are just my warnings, do whatever you want with them.
