In keyboard.c, under "case MOUSE_CLICK_EVENT:", step through the
code until you get to this line:

            position = make_lispy_position (f, event->x, event->y,
                                            event->timestamp);

then step into make_lispy_position, and see what it produces.

(I hope I got the code right; apologies if not.)
