vi mode and history-search key binding

vi mode and history-search key binding

[William Scott]

Hi:

Among my favorite keybindings are

      bindkey '\e[A'    history-search-backward
      bindkey '\e[B'   history-search-forward


Since I use vim instead of emacs, I thought I ought to at least try  
vi keybindings, although I think my brain is too hard-wired to make  
the switch.  In any case, the up and down arrows would be of more use  
having this altered binding. I tried this:

      bindkey '\e[A'  vi-history-search-backward
      bindkey '\e[B'  vi-history-search-forward

It appears to have no effect. Is this intended?

Thanks.

Bill Scott

This binds those keys in the main keymap, which by default is the emacs
keymap.  Have you somewhere earlier in your startup files executed a
"bindkey -v" command?  If you did, then those bind keys in the viins
keymap (insert mode), not the vicmd keymap (command mode).  In which
mode are you attempting to invoke the search?

The effect you should see is that a quetion-mark (for backward) or slash
(for forward) prompt appears below the PS1 prompt; you then enter the
string to search for.  If that doesn't happen, you've probably bound
the keys in the wrong keymap.

Sorry, I misunderstood what vi-history-search-forward, etc, does.

         bindkey -v
         bindkey '\e[A'  history-search-backward
         bindkey '\e[B'  history-search-forward

gives me the desired behavior.


Thanks for pointing out what should have been obvious.  (I just issued
bindkey -v on the command line to experiment. I'm not sure what it says
about the ossified state of my brain, but even as a vi(m) user, I can't
seem to break the emacs keybinding habbits in the shell. It was far easier
to switch from tcsh to zsh. I'll give it the weekend.)
