This is a hack of the UNIX shell command completion feature. You can type in the first few characters of a file name and then press a key to have the system complete it.
Navigate to:
HCU\ Software\ Microsoft\ Command Processor
And to:
HLM\ Software\ Microsoft\ Command Processor
Set the DWORD Value CompletionChar to equal the hexadecimal value of the control character for the required keyboard stroke. The hex values for the key combinations are as in “A Hotkey For Command Line Directory Completion.”
Use any hex values corresponding to the desired control character. The complete list of possible control characters can be found at http://en.wikipedia.org/wiki/ASCII. The representation is in the form ^letter, where ^ represents the [Ctrl] key. Thus ^Z = [Ctrl] + [Z], and has a hex value of 26.
Type in the first few characters of the filename and press the key to complete it. If you have multiple files that begin with the same character string, press the [Ctrl] key multiple times to cycle through the available list of files.
Use this in conjunction with “A Hotkey For Command Line Directory Completion.”
