Mac 101: Enter directory paths when in open/save dialogs - The Unofficial Apple Weblog (TUAW)
Saw this on TUAW, I've been looking for that functionality since I switched to Mac. Although it's useful to be able to specify a folder path and avoid having to traverse the folder lists, a bigger benefit for me is being able to specify a directory that you can't reach normally in an open/save dialog, /tmp
for example.
Thanks TUAW, I should probably read all the Mac 101 posts
