Windows XP cmd.exe file/directory name completion

In Windows XP, to enable/customize CMD.EXE file/directory name completion, open REGEDIT and go to this key:

HKEY_CURRENT_USER\Software\Microsoft\Command Processor

Here's some info on the values that may be present, and my own settings.

Value Name	Value Type	Default	My Setting
CompletionChar	REG_DWORD	0x06 (Ctrl-F)	0x09 (TAB)
PathCompletionChar	REG_DWORD	0x04 (Ctrl-D)	0x09 (TAB)
