How to simultaneously scroll two windows?

问题

I want to simultaneously scroll two windows, but the hotkey input method requires me to duplicate it multiple times. My idea is to use Function Hotkeys and A_ThisHotKey variable, but the WheelDown is disable in the program if using this script:

WheelDown::
ScrollKey := A_ThisHotKey
SetTitleMatchMode, 2
IfWinActive, Writer
{
        CoordMode, Mouse, Screen
        WinGet, active_id, ID, A
        IfWinExist, Sumatra
        {
                Send {ScrollKey}
                WinActivate ; Automatically uses the window found above.
                Send {ScrollKey}
                Send {ScrollKey}
                WinActivate, ahk_id %active_id%
        }
}
Else
{
        Send {A_ThisHotKey}
}
return

I want ScrollKey to match WheelUp, WheelDown, PgUp, PgDn, Up, Down.

Ideally, I think the script should detect how much the first program is scrolled, then apply that amount to the second one. Advantages:

Scrolling will be seamless since the other program are scrolled in the background
Clicking on the scrollbar works
Different scrolling speeds don't affect the comparison
Moving lines in text editors won't scroll pages in PDF viewers

^{FYI: Send/SendRaw/SendInput/SendPlay/SendEvent: Send keys & clicks

Try this

#SingleInstance Force
Process, Priority, , High

; SetTitleMatchMode, 2

GroupAdd, Scroll_Group, ahk_class Notepad
GroupAdd, Scroll_Group, ahk_class Notepad++

SetWinDelay 0

#If (WinActive("ahk_class Notepad") && WinExist("ahk_class Notepad++")) || (WinActive("ahk_class Notepad++") && WinExist("ahk_class Notepad"))

    WheelUp::
    WheelDown::
    PgUp::
    PgDn::
    Up::
    Down::  
        MouseGetPos, mX, mY
        Send {%A_ThisHotKey%}
        GroupActivate Scroll_Group  ; activate the next window of this group
        If (A_ThisHotKey = "WheelUp" || A_ThisHotKey = "WheelDown")
            MouseMove, 200, 200, 0  ; move the mouse over the currently active window 
        Send {%A_ThisHotKey%}   
        GroupActivate Scroll_Group
        MouseMove, mX, mY, 0
    return

#If

Based on user3419297's answer, this modified script allows you to define the titles of the two apps you want to scroll at the top of the script once:

#NoEnv  ; Recommended for performance and compatibility with future AutoHotkey releases.
#SingleInstance Force
SendMode Input  ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir%  ; Ensures a consistent starting directory.

Process, Priority, , High
SetTitleMatchMode, 2

; Set your desired app names here. It is enough to use a part of the window's title
PART_OF_TITLE_OF_APP_A := "Notepad++"
PART_OF_TITLE_OF_APP_B := "Word"

GroupAdd, Scroll_Group, %PART_OF_TITLE_OF_APP_A%
GroupAdd, Scroll_Group, %PART_OF_TITLE_OF_APP_B%

SetWinDelay 0

#If (WinActive(PART_OF_TITLE_OF_APP_A) && WinExist(PART_OF_TITLE_OF_APP_B))
    || (WinActive(PART_OF_TITLE_OF_APP_B) && WinExist(PART_OF_TITLE_OF_APP_A))

    WheelUp::
    WheelDown::
    PgUp::
    PgDn::
    Up::
    Down::  
        MouseGetPos, mX, mY
        Send {%A_ThisHotKey%}
        GroupActivate Scroll_Group  ; activate the next window of this group
        If (A_ThisHotKey = "WheelUp" || A_ThisHotKey = "WheelDown")
            MouseMove, 200, 200, 0  ; move the mouse over the currently active window 
        Send {%A_ThisHotKey%}   
        GroupActivate Scroll_Group
        MouseMove, mX, mY, 0
    return
