The only directories visible at that level are /Applications /Library /System /Users.  However, ~/Library is hidden.

I believe that /opt and certain other root directories are normally hidden unless you “show hidden files”  (also “dot” files).

This command is apparently still correct:  defaults write com.apple.finder AppleShowAllFiles TRUE;killall Finder

		defaults read com.apple.finder AppleShowAllFiles

On my iMac the Finder displays all hidden files.  
However, that does NOT have any effect on the selection display from within Safari (i.e. in Trac when trying to append a file to a ticket.)
