本模組可以產出一個文字方塊，顯示可連結至某個頁面的捷徑。

用法

用於Wiki標記語法

如果要從Wiki標記語法引入，本模板應當從某個模板進行呼叫，通常使用的模板為{{shortcut}}。請參考該模板的文件說明。然而，您也可以用Wiki標記語法進行呼叫：Template:Tlxm。

用於Lua

如果要從Lua使用本模組，首先請讀取本模板。

local mShortcut = require('Module:Shortcut')

然後您可以依據下列語法建立捷徑方塊：

mShortcut._main(shortcuts, options, frame, cfg)

• shortcuts為捷徑頁的名稱陣列（必填）。
• options為表格偏好設定，支援下列參數：
  • msg - 顯示捷徑列表之後的訊息。
  • category - 如果設為no，則隱藏分類，不建議使用。（調用Module:Yesno）
• frame a frame object. This is optional, and only intended to be used internally.
• cfg - 表格格式測試，正常情況下請不要使用，該參數應僅供測試。

技術細節

本模組有一份組態檔案Module:Shortcut/config。該檔案可將本模板翻譯成不同的語言，或是改變分類名稱的細節。
