KEYB.COM (MS-DOS)
-----------------
If you use command-line options to load KEYB.COM, it is
recommended that you load it before starting Windows.
After it is loaded, you can change the keyboard configuration
from an MS-DOS Prompt within Windows any time. If you do not
load KEYB.COM before starting windows, you may encounter
problems using a KEYB command that includes an option in an
MS-DOS Prompt. However, you can use the KEYB command without
options at any time to display code-page information.
