No, it doesn't seem to. One can't even select a whole transaction that  
way, which I guess is why the Transaction menu has its own cut/copy/ 
paste functions (which work fine under Quartz, by the way).

Gtk_selection_* is used only in src/register/register-gnome/gnucash- 
item-edit.c, and appears to be used only for operating on a single  
element in a transaction or split.
