"Close all the branches (hit the [ key) and then open a trigger.
Okay, now copy a trigger (right-click the main trigger's branch, above the geometry branch and select Copy) and then paste it by right-clicking on the main Triggers branch and then paste it."
Maybe I'm stupid but when i open .git file in k-gff where am i suppoused to open that trigger? In k-gff as well? Because from what I understand after I open somewhere the trigger there should be a node with geometry list and other nodes with positions.
