This function graphically identifies an object number (structure).
Click with the 3rd mouse button on the structure number in the CSS display
window to delete the corresponding structure or network and then redraw it in
order to highlight it (only driver X11 8887). This reveals which structure it
is possible to work on. As well as highlighting the graphics, the following
information is
displayed :
* number of elements in the structure
* status ( open / closed )
* position of the element pointer
* current edit mode
To clear this information, click again on the 3rd mouse button or ESC with the cursor inside the popup.
Note : This function is the opposite of the Pick Icon On / Off function that may be accessed from the Option menu.
