外掛功能 在excel裡面按快捷鍵(Alt+Shift+O)可以彈窗進行搜尋檔案，效果圖如下

選擇檔案可以進行跳轉，類似於Visual Studio助手的搜尋檔案功能一樣 好的 閒話不多說 程式碼放上

核心的程式碼就是上面這些，但是在釋出的時候卻遇到了一個問題，在win7上面執行好好地，但是在移植到win10上面的時候，發現一彈框就會出現假死的現象。經過排查發現是因為windows api SetWindowsHookEx函式所導致的，

此坑先佔位 等待後續解決
不過也發現了另外一個製作快捷鍵的方法，就是使用excel中this.Application.OnKey，如果沒有找到解決平臺不相容的辦法，打算使用這個來替換。
