Can you scroll the window in interactive substitute mode?

Question

I am using an interactive substitution that spans multiple lines. In order to determine whether each particular occurrence should be replaced, I need to see all lines that are included in the search criteria, but vim only displays the first line.

I know you can scroll the window with zz, zt and zb, but this doesn't appear to work in interactive substitute mode. Is there an alternative approach?

Here is an example command, which replaces three newlines with two:

:1,$s/\n\n\n/^M^M/gce

Answer 1

To answer my own question (and if I read the documentation on the [c] flag properly), I would have known that using CTRL-E and CTRL-Y scroll the screen up and down, respectively.

[c] Confirm each substitution. Vim highlights the matching string with...

CTRL-E to scroll the screen up {not in Vi, not available when compiled without the |+insert_expand| feature}

CTRL-Y to scroll the screen down {not in Vi, not available when compiled without the |+insert_expand| feature}
