Why can't you just answer my question? I had to spend five minutes studying your message to extract the answers. I take it these are the answers:

1. You want to press NumPad5 with your finger.

2. You want the local Shaiya to receive nothing.

3. You want the remote Shaiya to receive NumPad5.

Is that correct? Is that what you are trying to do?

but I tested HKN using local keys so when I press numpad 5 for it to press the number 3, it was able to send this key...
Are you saying that you wrote a hotkey definition that successfully injected a keystroke into the remote Shaiya? If so, please copy and paste that hotkey definition here so I can see what worked.

What I was saying is that would it be possible to press Numpad 5 on this PC and that to send the message to the remote PC to Press Numpad 5 which then uses the local script as this works for Shaiya, the method of s
HotkeyNet doesn't work the way you think it does. It doesn't make the slightest difference whether a hotkey is defined in a remote script or local script. Either way the remote copy of HotkeyNet injects the keystroke using exactly the same code.

There are many ways to use HotkeyNet to send to a window but since you are having a problem, and I do not know what the problem is, I can't answer the question until you give me the info that I requested.
