To make the cut/copy/paste keys work, you need to add an entry to 
$(sysconfigdir)/gtk-2.0/gtkrc like:

binding "clipboard-keys" 
  bind "F343" { "cut-clipboard" () }
  bind "F344" { "copy-clipboard" () }
  bind "F345" { "paste-clipboard" () }

class "GtkEntry" binding "clipboard-keys"
class "GtkTextView" binding "clipboard-keys"
I don't remember offhand what the exact function keys that Sun has
mapped these keys to are; experimentation with xev should reveal
it. (If there were actual specific key symbols for these keys, we
might ship GTK+ with them bound out of the box, but they are just
random function keys.)

Most accelerators were broken on Sun X servers for 2.0.0; fixed in CVS:

2002-03-15 Padraig O'Briain <padraig obriain sun com>

	* gdk/x11/gdkkeys-x11.c (update_keymaps): Fudge keymap to have lower
	upper case variants if there is only a single keysym per keycode and
	the key symbol has upper and lower case variants (#74512)

gtk_editable_copy_clipboard (GtkEditable *editable)
  g_return_if_fail (GTK_IS_EDITABLE (editable));
  gtk_signal_emit_by_name (GTK_OBJECT (editable), "copy_clipboard");

So, there was some infinite recursion going on...
