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.
