   > took me a while to realize that the "..." button transforms into a dropdown button which opens the special buttons popup and that mouse buttons don't automatically resolve into a value when you press edit.
   
   Yes. Have added a screenshot of this to the description.
   
   > (what confused me initially was that `xev -event button | grep button` uses different button numbers than java does, so either the linux distribution or java must map them somehow)
   
   Confused me for a while with `xev` too.  I realised that X11 is mapping the mouse wheel up/down as buttons 4 & 5, so these are skipped in Java's button numbering.
   
   Think it's explained by the code at https://github.com/openjdk/jdk/blob/master/src/java.desktop/unix/classes/sun/awt/X11/XWindow.java#L731
    
   > btw what is the forward/back action?
   
   An editor action, also in the editor toolbar.  Try `CTRL-click` on a method to open another method in the same or a different file.  Now try the back button (or in NB19 `ALT-LEFT`).  It's a multi-level navigation history - very useful when exploring code across multiple files.
