There is no way to copy to clipboard attributes in preview pane in component library

[Sergey Fukanchik]

1) Open gschem
2) Press i to add a component
3) Find a component with documentation attribute, for example sa52-11-1.sym
4) To the right there is an attributes pane. One of the attributes is documentation which points to PDF datasheet.
5) If someone wants to evaluate it there is no way to copy description or documentation value to clipboard or pass it to browser to open the URL.

E.g. rightclick does not open context menu or Ctrl-C does not copy anything to clipboard.
