Display hidden files hot key on Mavericks gone? On prior versions of OS X, it was possible to display hidden files in a Finder dialog box (Open, Save, etc.) using Command-Shift-Period.

In Mavericks, that feature isn't working for me. Is there another command that one can use? I would prefer not to globally enable hidden files.

EDIT: I'm the one offering the bounty. It seems I cannot comment because I don't have enough rep now :)

So... yes, I'm also running 10.9.1 and it does not work. I have used it in previous versions of OSX and it worked fine. The script mentioned is OK to show the hidden files in Finder, but it does not work that well when using the open/save dialog.

My use case: sometimes I need to open/save files to the /tmp directory. In previous versions of OSX I just used the dialog to get to the disk root, and then press CommandShift. and then I was able to see the /tmp directory (actually /private/tmp).

So, if you guys are using the same version of OSX and it does work for you, I guess there must be a way to re-activate this. Any ideas?
The key bindings doesn't work in Column view mode on Maverick, but it works in e.g. List view mode. Switching back to Column view mode after doing the toggle in List view mode then shows the hidden files.
