</div>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:12.0pt">I believe the community's interest in this feature can be demonstrated with three simple arguments:<br>
<br>
1. The amount of code needed to implement what you described is comparable to the size of the existing CodeArea itself.<br>
2. This feature already exists in RichTextFX (JavaFX) and RSyntaxTextArea (Swing).<br>
3. It’s also present in editors like NetBeans, IntelliJ IDEA, and VS Code.<br>
<br>
So, I think there’s every reason to add it to JFX CodeArea as well.<br>
<br>
Best regards, Pavel<o:p></o:p></span></p>
