Simple syntax: 
(:popiframe:)
%popframe%[[Group/PageName]]
%popiframe name=uniquetarget%[[Group/PageName| Title]]

Without name=uniquetarget, the href will target '#' for all links.  Thus
the browser will show all popiframe links as visited.  You can assign
unique arbitrary names to each popiframe to make it more realistic.
    
When using this recipe in display interior wiki pages, install the included
null skin and use something like: 
%popiframe name=uniquetarget%[[Group/PageName?skin=null| Title]]
