            e.column(col,minwidth=0,width=170)
e.pack()
e.insert("","end",values=("ss",66))
e.insert("","end",values=("yy",11))

You have to bind a callback function to the according keyboard event. The function itself needs access to the Treeview widget. You can do this by binding e in a closure:

root.bind('<Control-a>', lambda *args: e.selection_add(e.get_children()))
