<p>In SharePoint, it is easy to set up a List webpart consisting of Links to other documents, folders, sites, etc.  Unfortunately, when clicking these links, the default behavior is for the page to open in the current browser window.  That is, it does NOT open the page in a new instance of the browser.  This has proven annoying for a number of the users on my site.</p>

<p>Does anyone know of a way to have the default behavior be to open in a NEW browser window?  </p>

<p>I'm hoping this is something that can be set in SharePoint rather than having users need to adjust some sort of setting in their browser.</p>

It is not possible with the default Link List web part, but there are resources describing how to extend Sharepoint server-side to add this functionality.
