Recently changed behavior with moving between CTRL-R history search to vi mode

Recently changed behavior with moving between CTRL-R history search to vi mode

[Cory Klein]

Use case: Modify and run a previously run command.

Solution:

1. CTRL-R
2. search for command
3. ESC to end history search, placing result into command prompt
4. ESC again to enter vi mode
5. w/l/other vi movement key

However, recently I'm seeing that in some cases my shell is combining
the ESC from 4 with the movement key from 5:

ESC-w => delete from the beginning of the line to the current cursor position
ESC-l => insert "ls" in the current cursor position and execute the
command immediately (huh?)

I can get the original behavior back by hitting ESC one more time -
escaping whatever strange mode my prompt is in, and getting into vi
mode for reals.

Forgive me if this is not the correct forum for seeking help with
this, but does anyone here know what might be happening here, have a
solution, or a suggestion on where else I may look for more
information?

Thanks,

Cory Klein

This is the right place to ask, but I'm not able to reproduce a problem.
This bit --

} ESC-l => insert "ls" in the current cursor position and execute the
} command immediately (huh?)

-- makes me believe that some other bindings are getting involved.

Try this:

    PS1="%v |$PS1"
    zle-keymap-select() { psvar=("$1 -> $KEYMAP"); zle reset-prompt }
    zle -N zle-keymap-select

This should cause your prompt to look like e.g.

main -> vicmd |torch% 

after you hit the first ESC.  If that's not what it looks like, that is
if it says something other than "vicmd" to the right of the ->, then
whatever it does say will be a clue.

(If you're already using psvar / %v for some other prompt configuration,
there are other ways to display the same information.)
