Before You Begin

You must become an administrator who is assigned the solaris.admin.edit/etc/default/kbd authorization. By default, the root role has this authorization. For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.4.

  1. Change the value of KEYBOARD_ABORT to disable.

    # cat /etc/default/kbd
    # KEYBOARD_ABORT affects the default behavior of the keyboard abort

  2. Update the keyboard defaults.
    # kbd -i
