These functions are not built-in EFS extensions. They are user-defined functions similar to preMain() and main(). When one of these functions are present in the formula code, the corresponding mouse event will execute the code within the function whenever the event occurs.

Starting with version 11.1 all mouse functions require the use of the Shift key when called from the chart. This change was done to avoid conflicts between EFS and chart mouse events (such as right clicking or double clicking) without compromising any backwards compatibility.
