Hi, the use of the comma (,) is very useful, say you want an OP to navigate to "lan Settings" under connections in Internet options, from an elevated cmd prompt OR the search bar in Vista /Seven:-
Cmd prompt:-
C:\Windows\system32>Control Inetcpl.cpl,,4 (applies to most windows apps)
By default the first window is General then ,,4 for Connections if you wanted Programs ,,5
Just makes it easier for the poster to go where you want them, oddly enough I do not see this much, certainly at TSF.
