Navigation Arrow
Overview
Some of the designer tools show links to objects on any of the pages of your project. If a link is clicked, the designer jumps to the referenced object and a thick green arrow is show that points to that object.As soon as you shift the page, or switch to another page, the navigation arrow disappears again.
The navigation arrow always pops up at approximately the same place, shifting the page such that the object is pointed to by the arrow. You can change this spot by dragging the arrow to where it best suites you. The next time you click a link, the arrow will show up on its new position.
