Opening the Current Directory From the Command Line

Given my aversion to mice (the peripheral, not the mammal) I generally try to favor command line whenever possible.  However, I still sometimes find myself dropping into an explorer window to do things that would be inefficient at the command prompt.  Adding or removing multiple files to or from a Subversion repository comes to mind, as an example.

In these cases I always lost precious seconds opening the explorer window and then manually navigating back to where I was at the command prompt.  However, today I remembered that Explorer.exe accepts command arguments, and that '.' is apparently the universal symbol for 'current directory'.  Therefore, typing the following command at the command prompt immediately opens an explorer window on the directory that you're currently in.

Hope this saves you a few seconds, too.
