Can I open Explorer at the current path when working in Command Prompt?

Like this:

explorer .

The period being used to represent the current folder. Single one meaning this folder, Two of them, being the next folder up the hierarchy.

If at C:\Users\Bonzo...

explorer .

Opens up the folder C:\Users\Bonzo

explorer ..

Opens up the folder C:\Users, and

explorer ..\..

Opens up C:\

The dots work also with the cd command and pretty much anywhere else you need to specify locations.
