This program is an enhanced, drop-in replacement for the DOSKEY.COM that ships with MS-DOS and Windows 9x/Me.  Although enhanced, it has a smaller disk and memory resident footprint.  It is a great addition to DOS boot diskettes, and to the Win 9x/Me environment if the DOS box is used frequently.  Note: will not operate under Windows NT/2000/XP (it's not needed since those systems have completion mechanisms built-in).

The primary added feature is command and file "auto-completion" via the tab key.  Depending on the context, either a matching command or filename (or path) will be supplied.  This is a huge timesaver when using the command line.
