Meh. This is what I get for not trying things out...
autoload -Uz up-line-or-beginning-search zle -N up-line-or-beginning-search autoload -Uz down-line-or-beginning-search zle -N down-line-or-beginning-search bindkey '\eOA' up-line-or-beginning-search bindkey '\e[A' up-line-or-beginning-search bindkey '\eOB' down-line-or-beginning-search bindkey '\e[B' down-line-or-beginning-search
There seems to be a cosmetic bug that triggers the first time you use either of those (if you got warn_create_global set, which I do):
up-line-or-beginning-search:15: scalar parameter __savecursor created globally in function up-line-or-beginning-search:16: scalar parameter __searching created globally in function
you can do the following until you get a fixed up zsh version:
typeset -g __savecursor __searching
The 8 lines you posted works without the typeset bit. Thank you. I think others would like this functionality. Perhaps add it as a the grml default?
