I believe what you're looking for are the ``bindkey'' commands of the file
/usr/src/etc/root/dot.cshrc shown below:
# $FreeBSD: src/etc/root/dot.cshrc,v 1.28 2001/01/10 02:37:16 archie Exp $
#
# .cshrc - csh resource script, read at beginning of execution by each shell
#
...
if ($?prompt) then
# An interactive shell -- set some stuff up
set prompt = "`hostname -s`# "
set filec
set history = 100
set savehist = 100
set mail = (/var/mail/$USER)
if ( $?tcsh ) then
bindkey "^W" backward-delete-word
bindkey -k up history-search-backward
bindkey -k down history-search-forward
endif
endif
The ``bindkey -k up'' and ``bindkey -k down'' commands are tcsh-specific,
that's why they're wrapper in an `if (?tcsh ) then .. endif' block. Note
though, that you can't use these in older versions of FreeBSD where the
system /bin/csh was not tcsh.
