Supposing I have already set a guide in the manner described above and
later want to modify the exact position entered. How can I modify the
existing guide coordinate ?

Since there is nothing attached to a guide, you can delete it and
create one at the new position.
Or just move it with the mouse and watch the position indicator at the
bottom of the screen :<)

The trouble with that is the level of control is fairly crude.

I hit this recently in the context of cropping out a section of an image. I needed a 1024x1024 for an external FFT application. Doing that with the mouse is not very realistic.

I would have liked to use the arrow keys to fine tune the selection but as soon as I let go of the mouse drag operation the dimensions of the selection are not longer displayed.

This seems like an oversight since until the selection dimensions are confirmed the co-ords need to stay up.

I ended up cutting out larger and then using ImageMagick to finish the job.
