<div class="plain_line">Hello Mark,</div>
<div class="plain_line"> </div>
<div class="plain_line">As far as I know, the shortcuts are localisable. For example, you use</div>
<div class="plain_line">Ctrl+S to save a file in an English version, yet users of Spanish</div>
<div class="plain_line">version of Windows use Ctrl+G (for Guardar) instead.</div>
<div class="plain_line"> </div>
<div class="plain_line">At the same time, the most common actions — Cut, Copy and Paste as well as Undo and Redo — usually have the same shortcuts across all languages and OS, although macOS uses Cmd instead of Ctrl. However, the shortcut for Redo is not as standard, Ctrl+Shift+Z and Ctrl+Y are used, both could be mapped at the same time.</div>
<div class="plain_line"> </div>
<div class="plain_line">I wonder what is the shortcut for Undo in German versions since German keyboard layout has Z and Y keys swapped. Does anyone know?</div>
<div class="plain_line"> </div>
<div class="plain_line">So, the shortcuts used in an application are controlled by the application and the shortcuts can be localised.</div>
<div class="plain_line"> </div>
<div class="plain_line">For this reason, the shortcuts are usually “hardcoded”.</div>

<div class="plain_line"> 19), but I wouldn’t be surprised if it fails in other platforms /</div>
<div class="plain_line"> L&F’s. It feels brittle, but it might (?) have potential:</div>
<div class="plain_line"> </div>
<div class="plain_line"> private KeyStroke getCopyKeyStroke() {</div>
