Hi MrTom,
Thank you for asking. Yes I can understand that it is an odd request but it is someting I do need from time to time. Yes the use of the transform boxes .. and arrow keys for bump solved my problem here. Thank you.
Just for your information here is what I needed to do:
1) I am coloring illustrations for a book using Photoshop (line drawings by an artist colleguage)
2) I did the entire coloring and have my colors, shadows etc. in a number of layers organized in "groups" in Photoshop
3) In a meeting with the publisher yesterday he wanted on of the illustrations as front cover
4) this illustration was horizontal so needed to be changed to be usefull as a vertical cover.
5) so my artist colleguage has changed the size of the background lineart .. (he even stretched it in with somewhat).
6) NOW .. instead of re-coloring the image I wanted to re-use my current colors from the original image
7) So I copied over all my color layers for the background to the new file (I copied them all in one go by using the "layer > duplicate group" to the new file. I also copied over the original lineart to have something to visually ajust to)
8) Now reducing the opacity of the old line art for the color group and hiding the colors temporaly - all I now need to do is transform the color group to "align" with the new lineart (basically imitating what my artist colleguage did but with my color group)
9) To align those lines accurately I need to be zoomed way in while I do the transformation to be able to visually verify that the lines match up as accurate as possible.
Hope this clarifies

PS. Yes it would have been best if my artist colleguage had gotten my original coloring before ajusting the image - then I could have just ajusted my color group at the same time he ajusted his lineart. But he did not so I got the changed line drawing from him and had to "ajust" my colors acordingly.
