Reading coordinates from a 2D Plot

Hi,

In previous versions of Mathematica under Windows, you could read the 
x,y-coordinates of  a point, say the min of x^2 + 5. You could 
measure the minimum by clicking on the graphics and paste it in an 
input cell for further processing.
The coordinates were also displayed in the lower left corner of the window.

With repeated steps one could get a lot of coordinates and fit them 
with e.g. NonlinearFit.


How do I do it in Mathematica 6? I need this features badly for my students.
