Use the TEXT tool on a vertex. That’s the way to view the coordinates. You can just pull out the leader until the text shows the coordinates. Type esc. to NOT place the text.
To move use the move tool, click to grab the object at a point, make a move, then type the coordinates you want [x,y,z]. I don’t know if that’s in the documentation just learned about in forums. And then never used it. You can move any point, but AFIK only vertices display their coordinates as above.
