Canadian Keyboard Standard for the EngZish and French Languages
|Publication Date:||1 January 1992|
This Standard specifies requirements for keyboards to be used throughout Canada for word, information, and data- p rocessi ng applications.
This Standard defines the national keyboard layout (the primary keyboard layoup) providing access to characters most commonly used in Canada (group I chamctes) and a secondary keyboard layout which, when combined with the group 7 characters, supports the Latin alphabet No. 1 Graphic Set as defined in CSA Standard CANCSA-2243.4 and IS0 Standard 8859-1 (group 2a characters) or the Latin alphabet as defined in IS0 Standard 6937 (group 2&2b characters).
Support of additional groups is beyond the scope of this Standard. Additional groups may be examined for future inclusion. The group 2&2b characters provide a proper subset of the Videotefleletext Presentation Level Protocol Syntax North American PLPS character set as defined in CSA Standard T500. The keyboard layouts defined in this Standard may be used in these applications if full support is not required.
This Standard requires a 48-key alphanumeric area laid out according to IS0 Standard 99952 (see Figure 1) or a 47-key alphanumeric area laid out as specified in this Standard (see Figure 2), shift keys to provide access to group 7 characters, and optional group shift keys to provide access to characters from additional groups.
Alignment with CAN3-Z243.19 has been maintained where appropriate.
The secondary keyboard layout conforms to IS0 Standard 9995-3.
The selection or use of any particular communications protocol or coded character set is beyond the scope of this Standard. lB This Standard does not address the following : (a) transfer method or mechanism whereby a graphic symbol is displayed or printed; (b) technological or operational aspects of any particular implementation; (c) fonts; (d) placement of representation of a graphic symbol on any given keytop
