How to right-click on RH4? (to change displayed columns)

Hi!

On Hog4Pc I can right-click on the column headings in the Programmer/Editor window to modify the displayed columns (e.g. choose to "Show Note"). Is there a way to open this context menu on the RoadHog4 without external mouse? I tried Pig+Set or Pig+touching the column but nothing is happening.

Grateful for any help!! It's been a pleasure using hog so far!

Thanks, Axel
