[Gimp-user] Move tool specifics and paste alignment

[Michael Armida]

I'm getting used to the GIMP analogues to a few different operations I'm
used to under Photoshop, and having some trouble.  Two questions
relating to the move tool:

- I have read about the move tool modes and the ctrl-alt shortcut to
move a portion of a layer.  I would like to be able to do this and then
use the keyboard to move the contents of the selection, just like I
would by dragging the selection with the mouse.

- Once moving a selection, is there a way to make it only move in
cardinal directions?

Also, if I do need to resort to cutting out a portion of an existing
layer to reposition it, how do I paste it back in the same spot from
which it came?  When I cut out a selection and then immediately paste, I
currently get the floating layer repositioned near the top left of my image.

Thanks for your time and help.
