How to bind keys only for History Menu?

[JerryZhongJ]

I want to keep the default behaviors in zsh' history search, which is using ← and → to quit selection and move forward/backward a char in command, and pressing 'Enter' to run the command in the menu immediately. For now, when I find out a command from history menu, I need a double Enter to run it, which is quite inconvenient. If I want to modify the command, I need to press tab or Enter to quit the menu first, which I always forget, and this brings me a mess.

I tried the solution in README.md, but this does not only modify the key binding in History Menu, but also in Completion Menu.

bindkey -M menuselect '\r' .accept-line
bindkey -M menuselect "$terminfo[kcub1]" .backward-char
bindkey -M menuselect "$terminfo[kcuf1]" .forward-char      

But this is not what I want. When I press Enter in Completion Menu, what I mean is to select the item. And I can't move left and right among the items.

I know I can change the behavior of ↑ to the default of zsh, but I want to keep the History Menu because it is quite useful for me,

I think the solution is to change key binding only for History Menu. Can it be done?

I figure out a solution, that is adding a wrapper to the two widgets, history-search and complete-word. The wrappers call bindkey every time the widgets are called.

I add this to my .zshrc:

wrap(){
  functions[${1}:old]="$(
      unfunction ${1} 2> /dev/null
      builtin autoload +X -Uz ~autocomplete/Functions/Widgets/${1}
      print -r -- "$functions[${1}]"
  )"
  eval "${1}(){
    bindkey -M menuselect $terminfo[kcub1] ${2}
    bindkey -M menuselect $terminfo[kcuf1] ${3}
    bindkey -M menuselect '\r' ${4}
    ${1}:old \$@
  }"
}
wrap .autocomplete__history-search__completion-widget .backward-char .forward-char .accept-line
wrap .autocomplete__complete-word__completion-widget backward-char forward-char accept-line
unfunction wrap

However this solution is too ugly, and will break if the function names are changed. I'm looking forward to a better solution.

I used to have code like this inside the history widgets, but the problem is that the bindings don't get reversed when, for example, you abort the menu with ^C. Then you suddenly end up with these bindings in the completion menu, too, and that's not what you want.

@marlonrichert This is not going to reverse the key binding when you quit the menus, but reset it every time you enter the menus.

Yes, this is exactly what case me trouble as well. I've come to zsh from bash and I do like this history, BUT exactly as you told the needs of confirming command before I'm able to edit it somehow is really pain and switching next / previous one, when I hit the left/right and my intended command disappears, it drives me creasy too. This definitely makes sense to map like this by default (end history / search and start moving cursor in command prompt).

My people! I figured I was the only person in the world so annoyed by such a very specific thing! Tried to explain it to my wife and she just looked at me like 'why did I marry this person'.
