<p>ISO 9995-6:2006 <i>Function section</i> wurde am 8. Oktober 2009 zurückgezogen, da diese bei der Revision 2009 mit in die Norm ISO/IEC 9995-5:2009 <i>Editing and function section</i> (zuvor ISO/IEC 9995-5:2006 <i>Editing section</i><sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup>) integriert wurde.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup>
</p>
<div class="mw-heading mw-heading2"><h2 id="ISO/IEC_9995-3"><span id="ISO.2FIEC_9995-3"></span>ISO/IEC 9995-3</h2></div>
<p>ISO/IEC 9995-3:2010<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup> definiert eine sekundäre Zeichengruppe (<i>„common secondary group“</i>) für alphanumerische Tastaturen. Die Zeichen dieser Gruppe werden auf der rechten Hälfte der Tastenfläche dargestellt; die Norm legt ihre Positionen unabhängig von den im primären Layout vorhandenen Zeichen fest. Beispielsweise wird das <a href="../Yen" title="Yen">Yen</a>-Symbol „¥“ stets auf der Großbuchstaben-Position der 6. Buchstabentaste in der zweiten Reihe von oben dargestellt, also bei <a href="../QWERTZ-Tastaturbelegung" class="mw-redirect" title="QWERTZ-Tastaturbelegung">QWERTZ-Tastaturen</a> wie der deutschen <a href="../Tastaturbelegung" title="Tastaturbelegung">Belegung</a> auf der „Z“-Taste, bei QWERTY-Tastaturen wie der US-Belegung hingegen auf der „Y“-Taste.

</p>
</div>
<p>Zusätzlich definiert der Standard eine „nicht mehr aktuelle sekundäre Zeichengruppe“ (<i>„outdated common secondary group“</i>) ausschließlich für Kompatibilitätszwecke. Diese entspricht der in der früheren Norm-Version ISO/IEC 9995-3:2002 definierten „common secondary group“.

</p>
</div>
<p>Die <a href="../Diakritisches_Zeichen" title="Diakritisches Zeichen">diakritischen Zeichen</a> in der <i>„common secondary group“</i> sind <a href="../Tottaste" title="Tottaste">Tottasten</a>, d. h., sie werden vor dem Grundbuchstaben eingegeben. Dies gilt auch für Folgen von mehreren diakritischen Zeichen, wie sie z. B. zur Eingabe von <a href="../Vietnamesische_Sprache" title="Vietnamesische Sprache">vietnamesischen</a> Texten erforderlich sind.
</p><p>Weiterhin definiert ISO/IEC 9995-3:2010 eine Liste von „speziellen Zeichen, die als Kombination mit diakritischen Zeichen eingegeben werden können“ (<i>„Peculiar Characters which can be entered as combinations using diacritical marks“</i>). Diese Liste enthält Kombinationen aus je einem diakritischen und einem weiteren Zeichen. Beispielsweise kann das Ungleichheitszeichen „≠“ (<a href="../Unicode" title="Unicode">Unicode</a> U+2160) so eingegeben werden. Speziell Buchstaben mit einem horizontalen Querstrich (wie <a href="../Serbokroatische_Sprache" title="Serbokroatische Sprache">serbokroatisch</a> Đ/đ oder <a href="../Maltesische_Sprache" title="Maltesische Sprache">maltesisch</a> Ħ/ħ) werden so mittels des auf der »K«-Taste platzierten „Querstreichungsakzents“ eingegeben.
