The existing picking functionality in Salome is available on both meshes element and time stamps. It can be activated either from:
The menu bar: Selection ► Selection Info
The popup menu opened on a time stamp of the browser (see Gauss Points Geometry (new presentation)), item Selection Info
The popup menu opened on a presentation in the 3D view, item Selection Info
All these actions open a dialog box that drives the functionality.

The dialog allows user to graphically select an element and displays its corresponding information.

Selection is possible on:
Mesh element: node, edge, face and volume
Fields elements: cell, edge of cell
Graphic presentation of an object (actor)
When moving the mouse in the graphic area, any suitable element that is, corresponding to the defined filter is pre-highlighted (or detected) and displayed in shading for more convenience to the end user. When user presses the left-mouse button to select the detected element, it is redisplayed in another color, and the information related to the selection is refreshed in the dialog box, in the form of an array of data.
Since this behaviour does not fully correspond to EDF expectation, the picking function for results at Gauss point and Gauss point (geometry) will be redefined as described in the following paragraphs.
