; this has not been tested, but might work (I'm trying an even better way for now, activating WorkerW and then GroupActivate to go back)

#HotIf (WinActive("ahk_exe notepad.exe") || WinActive("- Visual Studio Code ahk_class Chrome_WidgetWin_1"))
;MButton::WinActivate("ahk_class Progman")
MButton::
{
    A_ControlDelay := -1 ; Changes only the control delay of the thread made for this specific hotkey
    global lastActiveWnd := WinExist("A")
    WinActivate("ahk_class Progman")
    ControlClick("x0 y0", "ahk_class Progman",,,, "Pos")
    HookEvent(EVENT_SYSTEM_FOREGROUND, HandleActivatedWindowTextEditorEvent)

    HandleActivatedWindowTextEditorEvent(hWinEventHook, event, hWnd, *)
    {
        try
            if (!WinGetClass(hWnd) = "Progman" || !WinGetClass(hWnd) = "WorkerW")
            {
                DllCall("UnhookWinEvent", "Ptr", hWinEventHook)
                global lastActiveWnd := unset
            }
    }
}

;#HotIf (WinActive("ahk_class WorkerW"))
#HotIf (WinActive("ahk_class Progman"))
MButton::try WinActivate(lastActiveWnd)
