; This is an EasyShift (ROCCAT™ Easy-Shift[+]™) implementation in AHK dubed - EasyAutoShift

; Initialize variables
global awaitingEASButton := false

; List of AHK keys: https://www.autohotkey.com/docs/v1/KeyList.htm
; Define the hotkey for XButton1 (Mouse4) press - EasyAutoShift button
XButton1::
    ; Set the flag to indicate that EasyAutoShift is pressed and awaiting scroll wheel event
    awaitingEASButton := true
return

; Define the hotkey for EasyAutoShift release - EasyAutoShift button
XButton1 Up::
    ; Reset the flags and state
    awaitingEASButton := false
return

; Check for scroll wheel actions and execute if EasyAutoShift was pressed
#If (awaitingEASButton)
    WheelUp::
        ; Perform the desired action when EasyAutoShift was pressed and then scroll wheel is moved up
        ; Replace the following line with your desired action
        MsgBox, Scroll wheel up action executed!
    return

    WheelDown::
        ; Perform the desired action when EasyAutoShift was pressed and then scroll wheel is moved down
        ; Replace the following line with your desired action
        MsgBox, Scroll wheel down action executed!
    return
#If

Personally, I use this for Volume control:

Send {Volume_Up}
Send {Volume_Down}

on the scroll events
