In VMD the coordinates of an atom you click on will be shwon in the console
after pressing "0" (zero, not O :) while the OpenGL display is in focus (or
selecting "Query" in the "Mouse" menu.

You can select an atom by giving an appropriate selection under
"Graphics"-"Representations"-"Selected Atoms" - like "x = 1.0 and y = 1.0 and
z = 1.0"...

Best,
  Michael
