The C-shell in Unix supports a special environment string setting called CSHEDIT. When you type the first few characters of a file
name and then press the Tab key, this option would search the working directory
and your path to complete the filename typing for you. If you want to try it,
you can apply the following registy hack for Windows NT or Windows 2000 :
Hive: HKEY_CURRENT_USER
Key:
Software\Microsoft\Command
Processor
Name: CompletionChar
Type: REG_DWORD
Value: 9 will allow Tab key to be completion character
