Consider setting up some default key bindings

[lnicola]

I've skimmed some of the various issues here and I understand that there's no single way to set the keybindings up, but I think the ones included in the README are fine and shouldn't conflict with anything else.

Can we add this (or something similar) as a default?

bindkey '^[[A' history-substring-search-up
bindkey '^[[B' history-substring-search-down

# Bind up and down keys
zmodload -F zsh/terminfo +p:terminfo
if [[ -n ${terminfo[kcuu1]} && -n ${terminfo[kcud1]} ]]; then
  bindkey ${terminfo[kcuu1]} history-substring-search-up
  bindkey ${terminfo[kcud1]} history-substring-search-down
fi
  
bindkey '^P' history-substring-search-up
bindkey '^N' history-substring-search-down
bindkey -M vicmd 'k' history-substring-search-up
bindkey -M vicmd 'j' history-substring-search-down

See for zimfw/zimfw#364 (comment) for some context, although it's probably not needed.
