Is there a key combination I can use to show/hide hidden items in Finder?
I don't think you can do this by default.
I myself use Hidden Files widget. it's so easy to use.
You can do it with two small shell scripts:
This will reveal the "invisible" files:
This will hide the "invisible" files made visible:
Save each into an appropriately named file, set their executable bits using
Alternately, you could use the following code, and toggle back and forth by executing the code repeatedly:
I have an AppleScript I use to toggle things like these off and on:
(Note, you can open up the downloaded AppleScript by dragging it to the icon of AppleScript Editor.app).
I generally prefer to tell applications to quit rather than kill them (though, with the sudden termination feature introduced in 10.6, that can sometimes be the same thing).
Oh, mine differs from Greg's in that I set it for the global preference domain (so that it affects all apps, including the Open and Save dialogs). (Though you can always toggle invisible files off or on in Open or Save panels using Command-Shift-period ).
