Links Message Box

The link message box is used to signal dependency problems when removing items from a tree (like functions and matrices).
Taking as example the matrices, there are possibly several items in the projects that are dependent by a matrix (functions that have it as input, presentations or charts that show it), therefore to remove a matrix you first need to remove all the dependent items from the project.
This error shows which items are dependent by the one you are trying to remove.

Clicking on one of the links selects and shows the item in its tree.

Clicking the Ok button this dialog is closed.
