In DxDesigner, suppose I want to select a part and then copy the part number assigned for that part into the Windows clipboard. How would I do that? In the Properties dialog box for the part, the part number is locked for editing (I can't go into edit mode, highlight it, and press Ctrl-C). In our designs, the library is locked.
Select the Part Number on the symbol directly in the schematic (from 7.9.4 onwards) by triple click of the mouse so that the text is clearly highlighted, then use the context menu to copy to the clipboard.
