如何使用 G 系列 Lua API v8.45 更改双击同一按钮时的按键按下方式

TIMEOUT = 15000`

当我找到并修改后，在LGS中将鼠标按钮4分配为CTRL键。但是存在一些错误，无法解决。太多的“ctrl + c”一次性复制和粘贴。

TIMEOUT = 15000

function OnEvent(event, arg, family)
        if event == "MOUSE_BUTTON_PRESSED" and arg == 4
            then
                if GetRunningTime() - (timestamp or 0) >= TIMEOUT
                then index = 0
                end

            index = (index or 0) + 1

            if index > 2
            then index = 1
            end

            if index == 1
            then PressKey("c")
            elseif index == 2
            then PressKey("v")
            end

            timestamp = GetRunningTime()

        elseif event == "MOUSE_BUTTON_RELEASED" and arg == 4
        then
            if index == 1
            then ReleaseKey("c")
            elseif index == 2
            then ReleaseKey("v")
end
end
end
