If you are doing a file comparison with an "All Scope" it should sync the cursor position between the two files when you press F6. I find I may use the comparison tool, and then need to copy or highlight data from one of the files, then when I push F6 it doesn't work as expected since the data being compared doesn't have the same offset.
Thank you again
