        win32api.keybd_event(117, 0, 0, 0)  # F6
        win32api.keybd_event(117, 0, win32con.KEYEVENTF_KEYUP, 0)  # F6
        time.sleep(0.5)
        win32api.keybd_event(9, 0, 0, 0)  # TAB
        win32api.keybd_event(9, 0, win32con.KEYEVENTF_KEYUP, 0)  # 释放按键
        time.sleep(0.5)
        win32api.keybd_event(40, 0, 0, 0)  # DOWN
        win32api.keybd_event(40, 0, win32con.KEYEVENTF_KEYUP, 0)  # 释放按键
        time.sleep(0.5)
        win32api.keybd_event(65, 0, 0, 0)  # A
        win32api.keybd_event(65, 0, win32con.KEYEVENTF_KEYUP, 0)  # A
        time.sleep(0.5)
        autoit.control_set_text("另存为", "Edit1", filePath)
