CSA keyboard

ACNOR is an acronym of the former French name (Association canadienne de normalisation) of the CSA Group,[3] a standards organization headquartered in Canada.

The cedilla key (dead letter) is still present in the secondary group 2a (see Figure 2) in the Canadian standard.

It is possible to completely do without the dead key for the grave accent, as the only three French letters that use it (À, È, and Ù) are directly accessible in both lowercase and uppercase on this keyboard.

Indeed, the use of this character as a diacritical mark allows writing only in a language other than the 14 officially supported languages on keyboards conforming to level B compliance (Albanian, German, English, Catalan, Danish, Spanish, Finnish, French, Italian, Icelandic, Dutch, Norwegian, Portuguese, Swedish).

In Figure 2, these two symbols (the macron and chief circle) are coloured purple, as they provide access to at least one character in Group 2a.

The symbol for selecting level 3 is represented in the ISO 9995-7 standard with two overlapping arrows, resembling a Christmas tree.

The labelling of dead keys with rectangles and the soft hyphen in parentheses (-), goes beyond Canadian and Quebec standards.

Figure 1: The Windows version differs from the official standard in terms of the location of dead keys (middle dot · , tilde ~ ) and the absence of a few characters, including đ , ⅛ and the dot above ˙ . The euro sign € was not included in the Canadian standard in 1992 and is not officially included in the standard yet (R2021). Microsoft added this symbol in 1999 (4 and E keys), following the ISO 9995-3 standard.
