On the FEMAP "Select" Toolbar, there's an option on the second icon to toggle on/off "Layers/Groups in Tooltips". If you toggle this on, when you are using the Select Toolbar to choose elements, nodes, etc. and you have the tooltips on, you will see Group and Layer information in the tooltip. In addition, if have the "Entity Info" pane open, you will see it there as well.
Mark.
