how do i use npc telepoting pet skill

The way i use it.. i click the drop box in the top right that says NPC information and click goods merchant or any npc that would be close to my quest and teleport there.

When you right-click on the pet skill it will bring up the world map.

At the top right of the map there will be a drop down menu in which you can choose the different kinds of NPCs available.

You can pick and choose which NPC is closest to the location you want to teleport to.

This can be done from one section of the map to another, not just in the map the skill brings up (you can do that by right clicking again then picking another section of the map you want to teleport to).
