[X-Newbies] Open folder in new window

[Steven Rogers]

OK - here's a simple one. Remember how Mac OS had the option to open  
double-clicked folders within the same window, or in a new window?   
Is there a way to do that at all in OS X? Even a script to add that  
to the folder context menu would work.  I found a bunch of keyboard  
shortcuts here:

The option key will make the selected folder open in a new window,  
but it also closes the current window . . . close, but not it. Its  
kind of a small thing, but I've been missing this for ages.

Anyone have any ideas?

Thanks,
SR
