Worked it out. PowerBook don't have right click. Have to use gesture or shift lick commodity
Indeed it's listed as gesture, but it's the way most laptops do it today: A two finger tip does the right click.
Preferences -> touchpad. Checkmark at "gestures" "use two fingers for a richt button click".
Can't remember when I used a physical right button on a laptop for the last time. It's pretty quick and convenient, albeit a little too sensitive on MorphOS for my taste.
