Hi guys, i would like to know how to make a very simple macro,i need to spam the key "K", possibly every 0,1 - 0,2 seconds (anything that is between in the range of 5-10 press per seconds is fine) so,i need to spam "K", infinite loop that and having another key to start/stop the macro. Thanks to everyone in advance! Big hugs from Italy! P.s. I promise I'll start studying how the program works,but right now i'm a little bit in a hurry and i never used it
