Add a new keyword

Specs:
Product Version: Apache NetBeans IDE 25
Java: 24.0.1; Java HotSpot(TM) 64-Bit Server VM 24.0.1+9-jvmci-b01
Runtime: Java(TM) SE Runtime Environment 24.0.1+9-jvmci-b01
System: Windows 11 version 10.0 running on amd64; UTF-8; en_US (nb)
User directory: C:\Users\arbol\AppData\Roaming\NetBeans\25
Cache directory: C:\Users\arbol\AppData\Local\NetBeans\Cache\25

In regards to the above specs, is it possible to add a new keyword to Netbeans when programming in Java?
I remember being able to do this using code::blocks long time ago.

Thanks in advance.
