This little program has saved me a lot of keystrokes and time.  
I found the basis for this program in PC Magazine's first issue of 
DOS Magazine.  I created the batch file as it was notated and then I added
some specifications of my own.  A version that would be usable for most
IBM compatible machines is listed below:
        CTRL-R=CHANGES TO ROOT DIRECTORY
        CTRL-U=GOES UP ONE DIRECTORY LEVEL
        CTRL-D=DISPLAYS DIRECTORY OF FILE NAMES AND EXTENSIONS
        CTRL-T=TYPE*
        CTRL-K=COPY*
        CTRL-N=RENAME*
        CTRL-E=ERASE*
        CTRL-A=GOES TO A: DRIVE
        CTRL-B=GOES TO B: DRIVE
        CRTL-C=GOES TO C: DRIVE
        CTRL-S=CLEARS THE SCREEN

        * = YOU MUST FOLLOW THESE COMMANDS WITH A SPACE AND
        COMPLETE FILENAME OR PATH NAME...
The ZIP file, FUNCTION.ZIP contains this text file plus the original batch 
file. Simply type FUNCTION to get a list of keystroke commands.
