Hi, I would like to know if it is possible to record a keyboard sequence with AutoIt. I don't want to send keys but to hold them for a certain time. I'm not sure if I'm very clear as I'm french and don't speak very good english... I would like to tell AutoIt to press the key A for like 10 seconds. But I think the hardest part is to record the sequence I need, because it could be A for 6.49 seconds and then K for 2.94seconds etc. I know the software Hot Keyboard Pro can do that but it would be useful for me to do it with AutoIt Thanks for your help
