I use vim for essentially all my editing needs, so I decided to once again try vi-mode for my shell (currently ZSH w/ oh-my-zsh on OS X), but I find myself trying (and failing) to use Ctrl-R constantly. What's the equivalent key-binding? And for future reference, how would I figure this out myself? I'm pretty sure I could use bind -P in bash.

According to 'man zshzle', history-incremental-search-backward is not bound in Vi modes (vicmd, viins) by default. –  paul Jul 27 '12 at 13:45

You can run bindkey with no arguments to get a list of existing bindings, eg:

# Enter vi mode
chopper:~> bindkey -v

# Search for history key bindings
chopper:~> bindkey | fgrep history
"^[OA" up-line-or-history
"^[OB" down-line-or-history
"^[[A" up-line-or-history
"^[[B" down-line-or-history

In emacs mode, the binding you want is history-incremental-search-backward, but that is not bound by default in vi mode. To bind Ctrl-R yourself, you can run this command, or add it to your ~/.zshrc:

bindkey "^R" history-incremental-search-backward

The zshzle manpage (man zshzle) has more information on zsh's line editor, bindkey, and emacs/vi modes.

Thanks, particularly for zshzle. That is quite informative and useful. –  Hank Gay Jul 27 '12 at 15:27
