Hi Anna,

Command-Shift-C is one of a class of Finder shortcuts for navigating  
to frequently used directories.  Take a look at Tim Kilburn's  
VoiceOver shortcuts page for a summary:
http://homepage.mac.com/kilburns/voiceover/shortcuts.html

I'll excerpt from his listing of "SHORTCUTS IN SAVE & OPEN DIALOGS":

        • cmd-shift-a - applications: Brings focus to the applications folder.
        • cmd-shift-h - Home: Brings focus to the user's Home directory.
        • cmd-shift-d - Desktop: Brings focus to the desktop.
        • cmd-shift-u - Utilities folder: Brings focus to the Utilities folder.
        • cmd-shift-i - idisk: Brings focus to the user's iDisk.
        • cmd-shift-c - Computer: Brings focus to the users computer so that  
attached drives and removable media can be easily accessed.
        • cmd-shift-g - Go to folder: this is especially useful for accessing  
areas that are normally invisible to the GUI.

Command-Shift-C will also show you other volumes connected and mounted  
on your computer, such as external hard drives, memory keys, some  
other MP3 players (that use USB mass storage conventions -- such as  
the Creative Muvo players), your iPod or Shuffle if you have disk mode  
activated.  New applications that are downloaded as files with .dmg  
extensions have privileges like disks in the system (they are treated  
like "disk images" for the installation process), which is why Søren's  
description of viewing them with Command-Shift-C and ejecting them  
with Command-E after the installation is finished is apt.

You don't need to keep disk image files once you've installed an  
application (unless you think this version is going to disappear --  
like keeping a copy of a "Free" application in beta so you can install  
this on other machines).  If the installation is successful, and you  
have a copy of the installed task in your applications folder  then  
you can send the .dmg file to the trash after you've ejected it.

Applications that require installers (generally, these are ones that  
need to exercise some control of other applications) will come with  
uninstallers.  The actual applications are actually "bundles".  If you  
like, you can select one of the apps in the Applications folder in  
Finder and use the contextual menu (VO-Shift-M) to choose the "Show  
Package Contents" menu option, then navigate through the contents.

HTH

Cheers,

Esther
