nomatch
Summary
The nomatch rule is fired if no other rule is matched or fired in
the same group, with some caveats.
Syntax
nomatch > ...Description
nomatch is similar to the match rule, but instead of the
rule being fired when a rule was matched, it will be used when no rule
is matched in the group. A nomatch rule can include use()
statements, return statements, beep
statements and characters.
Caveat: nomatch will not be fired in a using keys group if the
current keystroke does not produce a character in normal use (for
example, modified keys, function keys). This is by design, and is
intended to ensure that function keys, and modified keys such as Ctrl+X,
were passed through to the underlying application.
Examples
Example: Using nomatch
begin > use(constraints)
group(constraints) using keys
c Block two diacritics on one vowel
any(vowel) any(diacritic) + any(diacriticKey) > context beep
nomatch > use(main)
group(main) using keys
+ any(diacriticKey) > index(diacritic, 1)Platforms
The nomatch rule can be used in keyboards on all platforms.
