repeater , word typer

This is the first program i make in my life and because of this , this program will be full of bugs that i may or may not fix,  sooo about that program , this program repeats exactly what u write in it  very fast as it was written by keyboard  not copy and paste , by a click of a checkbox you can loop it , it will not respond for some reason and it will not work  but you can close it and open it again (I recommend not to use that checkbox it's cursed! FOR REAL DON'T USE IT I'VE WARNED YOU!!!! )
