Should AHI Support Low-Level Interception of Huion Tablet Keys (F13–F24)?

[hsayed21]

Description

I have a keyboard that only supports F1–F12.
What I am trying to do is use my Huion Tablet buttons to extend this functionality by mapping them to F13–F24.

• With AutoHotInterception, I can intercept F1–F12 fine.
• But when I try to assign a Huion Tablet button to F13–F24 in the Huion driver, AHI does not intercept anything.

Example Script

Here’s a minimal AutoHotInterception script I use for testing:

#Include Lib\AutoHotInterception.ahk

AHI := AutoHotInterception()
keyboardId := AHI.GetKeyboardId(0x0C45, 0x5004)  ; Adjust VID/PID

; Intercept F1 and block it
AHI.SubscribeKey(keyboardId, GetKeySC("F1"), true, F1toF15)
return

F1toF15(state) {
    global AHI, keyboardId
    ToolTip("Intercepted F1 -> Sending F15`nState: " state)

    ; Send F15 (scan code)
    AHI.SendKeyEvent(keyboardId, GetKeySC("F15"), state)

    Sleep(100)
    ToolTip()
}

Esc::ExitApp

When I press F1 on the Huion to assign it as F15, but nothing is intercepted.

What I Want

I want to press a Huion Tablet button → and make Windows/AutoHotkey see it as F13–F24.
This way I can expand my shortcuts beyond F1–F12, since my main keyboard doesn’t have physical F13–F24 keys.

Question

Since AutoHotInterception is supposed to work at a low level, shouldn’t it also be able to intercept Huion’s F13–F24 mappings?

Is this a limitation of how Huion sends input, or should AHI still be able to capture and remap these at a lower level?
