I absolutely love how zsh implemented the prefix search with an "arrow-up" key.
this feature is extremely useful for a long commands with lots of arguments, such as starting docker containers.
but! arrow keys are not so convenient to reach, especially when you touch-type-wannabe.
let's remap the ctrl+p, which is usually stands for "scroll history back",
to do the same as "arrow-up" in zsh:
bindkey "^P" up-line-or-beginning-search
bindkey "^N" down-line-or-beginning-search
