in reply to Invoking the Windows command line for selected directories
Not Perl, but similarly handy is the "Open Command Window Here" PowerToy free from Microsoft.
Another fun thing is "start some_dir" from the command line to pop up a file explorer for that directory. (E.g. "start ." to see the explorer for the current directory).
start has other neat uses. Given a filename, it will open the file up the default app for that filetype. Handy for .html files, for example. Type "help start" at the command line for more details.
