cmd.exe - file and directory name completion

If cmd.exe is started with the /f:on (or simply /f) option, the names of files and directories can be completed by (repeatedly) pressing a specific character.

By default, the character to complete directories is ctrl-d, the character to complete files is ctrl-f.

In Windows 10, ctrl-f is also the character to search for text if *Enable Ctrl key shurtcuts* is enabled. In that case, ctrl-f cannot be used to search for text.

The character that triggers filename and directory completion can be be changed in the registry in the values CompletionChar and PathCompletionChar below the registry key HKEY_CURRENT_USER\Software\Microsoft\Command Processor.
