+\subsection{Windows Shortcuts}
+\label{ref:Winshortcutsplugin}
+
+This plugin follows Microsoft Windows Explorer shortcuts (\fname{.lnk} files).
+In Rockbox, these types of shortcuts will show up as \fname{.lnk} files. To
+follow a shortcut, just ``play'' a \fname{.lnk} file from the file browser.
+The plugin will navigate the file browser to the linked file (which
+will be highlighted) or directory (which will be opened). Linked files will
+not be automatically opened; you must do this manually.
+
+Only relative links across the same volume are supported.
+
+\note{You may like to use native Rockbox shortcuts instead. These can be
+    created from within Rockbox itself and have advanced capabilities.
+    See \reference{ref:Shortcutsplugin}.}
