The solution is very simple: Select a pair of coordinates in your graphic
with the mouse, click left and release, press Ctrl-C (that is, do not
release the Ctrl key, just press C). Then move the cursor to an input cell
and press Ctrl-V. You will get your coordinates as a list of two real
numbers.

BTW, you can also select several points at once that way.
