Peter,

I think Example_6_2.py demostrates this, and the event is also
noted on page 618.

However, this snippet tracks the motion of the mouse without
a button down...

from Tkinter import *

root = Tk()

def motion(event):
    print 'Mouse: x=%d, y=%d' % (event.x, event.y)

frame = Frame(root, width=250, height=250)
frame.bind('<Motion>', motion)
frame.pack()

root.mainloop()

   John
