You could write, or hunt up, a "Character Map" like in start->programs->accessories->systemtools->. Mine has U-007C: Vertical Line. An x web browser on a wikipedia page for unicode would give you a bazillion glyphs. I get vi/vim has some octal/hex input feature somewhere. http://vim.wikia.com/wiki/Entering_special_characters

I am a big fan of the "set -o vi" mode of ksh/bash command line editing, not the bash thing so like DOS. In fact, I never leave $HOME except insice () so my commands when recalled all work. With X and command recall and vi command editing, you do not need the path shortening keystoke savings of cd. I usually make $HISTSIZE big, something like 32767 seems to all it can handle, move the $HISTORYFILE somewhere permanent, save it periodically in an archive, and write scripts to search it and display it so I can recall keystrokes for years. For long lines, you have to go exc-v-enter into vi every time, as they recall truncated, but they recall. Now, if you have or install vim, you export EDITOR=vim and poof! vi is not hard wired. I use vix, a script that, before running vi, echos out linefeeds to save the screen in the scrool buffer, and after running vi, returns 0 always, as when command line editing, return not zero from vi (any beep for trivial error) and the vi file is discarded.

Code:

$ cat mysrc/vix
#!/usr/bin/ksh
(
 stty -a | sed '
        s/^/ /
        t a
        :a
        s/.* rows = \([1-9][0-9]*\).*/\1/
        t
        d
        ' | read zr
# echo $zr >&2
 if [ "$zr" = "" ]
 then
  zr=25
 fi
 while [ "$zr" != -1 ]
 do
  zr=$(( $zr - 1 ))
  echo >/dev/tty
  done
 vi "$@"
 exit 0
)

I think the parens are for one aix or hpux system where the ksh, upon detecting the call of a ksh script, ran scripts in the login ksh, as if sourced. My environment kept getting trashed. My vix did not seem to work well on later x and vim, but it helps. I keep my xterms with huge scroll buffers running for weeks under vnc, where you can disconnect and reconnect to your remote per-host X desktops. Keystrokes are so valuable.

They really did not map 0174 onto the keyboard anywhere? How anti-ascii ! Rule Britannia!
