Auto Hot Key Script Help?

Pulll-eeee-sss-eee, if anyone could produce a working Automotive Hotkey script that will presses the particular ‘G’ key about the keybored the minute I press down this the remaining mouse control key I’ll give you a 5 star best solution and I’m going to greatly apreciate that.

To help clarify:
Customer presses:Remaining mouse
Script clicks:G when (when kept mouse is definitely pressed yet again G will probably be pressed once again.

It’s safe to doing average joe but the programing knoledge is definitely pretty minimal D:
Maybee certainly one of you very good people know more than a great amature similar to me; ).

Its Easy as Heck; )
This is the rule:

LButton::sendinput g

Regards!!
