fine line-by-line cropping

I am scanning old school photos. The photos are glued to colored paper
to serve as a frame.

I scanned them revealing some of the frame since I didn't want to
leave any part of the original photo out.

Is there a way to do a careful fine crop on each 4 sides removing
lines of pixels one at a time with a repeated key stroke.

I know about adjusting Canvas Size, but it's slow.

I used to run into a similar problem doing film scans and picking up
parts of the mount ... one easy way is to use the Crop tool, set the
'shield' option, zoom out so you can see the entire image and draw the
crop box, go to 100% zoom and look at the corners and adjust the crop
box as needed, then accept the cropping.

If the background (outside the frame) has a singular color, (or can be
selected using the magic wand), then you can use the TRIM option.

Otherwise, if you want one-pixel cropping horizontal or vertical, go to the
marquee selection. It has one-pixel vertical and horizontal options. Just
click to make the marquee, and arrow keys to move it.
