The D and + in flight plan

Hello all,
What is the difference between selecting a waypoint as direct or just add it to the FL ?

Waypoint helps you add it to your FPL (+) and the ā€œDā€ means directly to that point. (Destination)

If you choose the ā€œDā€ button, you can only select one waypoint (origin-destination)

While if you use ā€œ+ā€ button, you can select multiple waypoints to your destination (origin - Waypoint A - Waypoint B - destination)

I hope this helps! šŸ˜Š
