Digital BW, The Print

I've been going semi-bonkers the last little while, try to see the cursor
while spotting middle grey areas of my images. I was just about to post a
message asking for help, when I discovered a little trick I'd like to share.

Pressing the alt key once changes the cursor back to the readily visible
mouse arrow, making it easy to position in the right place. Pressing it
again restores it to the (in my case) brush-sized cursor.

Maybe I don't need new glasses after all.
