Make Zle act in the manner of many IRC clients by allowing the user to type something, press down arrow to get a blank input line, type something else and execute it, then press up twice and get what was typed previously (but not executed). From Bart;

First, a "fake-accept-line" to not really execute the command, but put it on the history. There are several different ways to do this with preexec hooks etc., but let's just do it the old-fashioned way:

fake-accept-line() {
  if [[ -n "$BUFFER" ]];
    print -S "$BUFFER"
  return 0
zle -N fake-accept-line

Next you want a function that does down-line-or-history unless there is nowhere to go (and no new line in a multi-line buffer), in which case it does fake-accept-line.

down-or-fake-accept-line() {
  if (( HISTNO == HISTCMD )) && [[ "$RBUFFER" != *$'\n'* ]];
    zle fake-accept-line
  zle .down-line-or-history "$@"
zle -N down-line-or-history down-or-fake-accept-line

to bind this to the existing key for down-line-or-history, or

bindkey '^[[B' down-or-fake-accept-line

that is if ^[[B is your terminal's down arrow.
