When using the command prompt console in Linux/Unix, then one quickly gets used to the TAB-key being able to complete the name of the file or directory that reside in the current directory. For example one is standing in the root directory "C:\", and wants to change directory to "C:\Windows". This can be done by writing "CD W" and then press the TAB-key, which will replace "W" with the first file or directory that starts with "W".

To specify which shortcut-key that should be used for file- and directory-completion add/update these DWORD registry values:

[HKEY_CURRENT_USER \Software \Microsoft \Command Processor]
CompletionChar= 9 (ASCII value for TAB)
PathCompletionChar= 9 (ASCII value for TAB)

Another way to get completion is to start Cmd.exe like this, where you will use CTRL+D(ASCII value 4) to complete pathname and CTRL+F(ASCII value 6) to complete filename:

cmd /f:on
