In Windows SharePoint Services 3.0 (WSS 3.0) or Microsoft Office SharePoint Server 2007 (MOSS 2007), administrators can easily create a hyperlink in the top link bar by selecting Site Action, choosing Site Settings, clicking Top link bar, and entering a hyperlink (e.g., http://www.officesharepointpro.com). One SharePoint question I'm often asked is how to create a hyperlink that opens a separate Microsoft Internet Explorer (IE) window.
There isn't an out-of-the-box solution for opening a link in another IE window. If you search the Internet, you'll find some solutions such as using Microsoft Office SharePoint Designer 2007 to modify the hyperlink or creating a new custom site definition that provides an "Open in New Window" option. These solutions might not be suitable for administrators who don't have SharePoint Designer 2007 or an in-depth understanding of SharePoint custom site definitions.
For example, suppose you want to open the Office & SharePoint Pro website in a new browser. You'd select Site Action, choose Site Settings, and click Top link bar. Then you'd enter
The Office & SharePoint Pro website will then open in a separate window while the SharePoint site remains open in the original window.
