#117 no copy&paste from Browser/Doc to Source

[BastelBarney]

One cannot copy / paste examples or text fragments from
internal browser and/or documentation viewer into one
of the sourcecode windows.
This must be come from omitted "Edit" Dialog in both
the browser views. Since this is very helpful to
copy&paste code snippets from the online documentation
into my own source, I would prefer to use that feature,
again.
