/***

一個用處不大的腳本，主要是我的另一個腳本圖片全載，需要手動確認網站存活時會用到。

注意一次性打開太多鏈結會造成瀏覽器嚴重卡頓，慎用！！！，在有需要的時候再開啟這個腳本。

說明

模式一：批量打開文字鏈結

創建一個文字輸入區，一行一個網址或域名，批量打開。

模式二：選取鏈結後打開

步驟1.透過腳本管理器選單或按快捷鍵Ctrl + Alt + U或雙擊頁面的空白處來注入事件。

步驟2.鼠標懸停要打開的鏈結進行標記和預讀，標記會對鏈結添加橙色的邊框，再次懸停會取消標記。

Q：如何中途取消？
A：按Esc鍵或點擊頁面的空白處。

步驟3.頁面的空白處按滑鼠右鍵或快捷鍵Ctrl + Alt + O，打開被標記的所有鏈結。

再次使用重複步驟1
