Copy full path when hovering over a file?

[Dov Grobgeld <dov grobgeld gmail com>]

Is there any keybinding that allows copying into the clip-board the full
path of a filename that you hover over in the file chooser dialog? E.g.
when looking at the "Recent file" menu, there is a tooltip popup of the
full path of a file. Is it possible to copy the contents of this tooltip so
that you can later paste it as text?

Thanks!
