In XP, to ensure a folder opened in a new window, I held down CTRL when I opened (by mouse or keyboard) the folder.
This action is so ingrained to me, I pretty much don't even realise I'm doing it at a conscious level.
Unfortunately, this action apparently hasn't made it to Vista. Is there a new way to do this, or am I just missing something obvious?
EDIT Looks like not possible in Vista, but returned in Win7. Answer selected as it mentioned a keyboard alternative in Ctrl+N.
