This feature is new in the Solaris 9 4/03 release.
Software support for three additional keyboards has been added to the Solaris 9 4/03 release: Estonian keyboard Type 6, French-Canadian keyboard Type 6, and Polish programmer's keyboard Type 5. This software support gives users in Canada, Estonia, and Poland greater flexibility for keyboard input. The support modifies standard U.S. keyboard layouts to different language needs.
