I rigged up a function that makes navigation super fast in zsh. If you
hit enter on a blank line, it runs ls automatically.
Just add the following to your .zshrc:
auto-ls () {
if [[ $#BUFFER -eq 0 ]]; then
echo ""
ls
zle redisplay
else
zle accept-line
fi
}
zle -N auto-ls
bindkey '^M' auto-ls
To get the ^M correct in vim, hit <Ctrl+V><Enter>. You could really
make this run whatever you want, on any key you want, but I like this
shortcut in particular (It goes great with autocd!).
Cheers,
Mitch

A (slightly) more generic way to do it would be
auto-ls () {
if [[ $#BUFFER -eq 0 ]]; then
echo ""
ls
zle redisplay
else
zle .$WIDGET
fi
}
zle -N accept-line auto-ls
zle -N other-widget auto-ls
This uses the same function to wrap any widget, ie you might want it
on accept-and-hold and accept-line-and-down-history as well, or
something. Maybe not. Note that the . in .$WIDGET is important, or it
will call the wrapper recursively, .foo always calls the builtin
widget ignoring any custom widgets by the same name. (And $WIDGET is
obviously the name of the widget that caused the function to be
called).

I like that method more, it's like a hook of sorts. For me I had to
add the line:
> zle -N auto-ls
before the line:
> zle -N accept-line auto-ls
otherwise it would complain that there's no widget 'auto-ls'.
I'm wondering what other cool tricks this could be used for :)
