I am = working on a widget for fuzzy search history.

....=
skim-history() {
=C2=A0 origquery=3D${BUFFER}
=C2=A0 outpu= t=3D$(history -1 1 | sd '^[ ]*[0-9]*[ ]*' '' | sk --tac --n= o-sort --exact)

=C2=A0 if [ $? -eq 0 ]; then

=C2=A0 else
=C2=A0 =C2=A0 BUFFER=3D$origquery
=C2=A0 fi=

=C2=A0 CURSOR=3D$#BUFFER
}

zle =C2=A0 =C2=A0 -N =C2=A0 sk= im-history
bindkey '^R' skim-history
....

In `history -1 1 | sd '^[ ]*[0-9]*[ ]*' ''= | sk --tac --no-sort --exact`, sd is used instead of sed, which=C2=A0just = removes numbers from the beginning. However, it messes things up if the com= mand is multi-line.

What I found is, the only way = zsh history=C2=A0parsing works correctly is if I use something like !NUM, t= o get the history. How can I edit my zle extension to do that?
Another option is (if previous fails), do not save multi line = commands in history. How can I do that?
