A common requirement in all SharePoint projects that I’ve be working on is to see what an end-user / visitor will see. The publishing console have the option “preview in another window” but you need to have the console activated / displayed and it’s not always obvious for someone who doesn’t know where to look for such an option. Fortunately, it’s really easy to add a simple link in your page layout (or master page in any “toolbox area”), just use the current page url and append
?PagePreview=true, a target=_blank will finish the job to keep the current page being edited opened !
GroupId = “SiteActions”
Title=”Preview page in a new window”
Hope it helped !
