The CASE option on the KEYBOARD configuration entry allows you to cause all entries to be automatically converted to upper or lowercase. value may be set to Upper, Lower or Both:

Upper: all ACCEPT statements convert keystrokes to upper case.
Lower:     all ACCEPT statements convert keystrokes to lowercase.
Both: (default) causes no translation.

CASE may be overridden with the settings of the UPPER and LOWER keywords on individual ACCEPT statements. See Common Screen Options for more information.

The configuration variable KBD_CASE is also supported.

Note: The value of KEYBOARD CASE does not affect controls. To effect the same result on controls, use the UPPER or LOWER phrase on the ACCEPT statement.
