~~# Minimum Working Example~~
To reproduce:
1. Add `bindkey -v` to your `~/.zshrc`.
2. Invoke python interpreter: `python`.
3. Type something into the prompt without hitting `ENTER`: `this = "this" + "that"`.
4. Press `ESC` and try any `vim` bindings successively: `bb`.
# Problem
The behavior is not consistent. Sometimes the cursor highlighting does not match the mode (see Notes for code used), sometimes I have to press `ESC` before each `vim` key entry.
# Notes
Using Arch Linux, `st` terminal, `zsh`, and `python` 3.10.9.
I am using the following code in my `~/.zshrc` to change the cursor to indicate mode:
```sh
# change cursor shape for different vi modes
cursor_mode() {
# See https://ttssh2.osdn.jp/manual/4/en/usage/tips/vim.html for cursor shapes
cursor_block='\e[2 q'
cursor_beam='\e[6 q'
function zle-keymap-select {
if [[ ${KEYMAP} == vicmd ]] ||
[[ $1 = 'block' ]]; then
echo -ne $cursor_block
elif [[ ${KEYMAP} == main ]] ||
[[ ${KEYMAP} == viins ]] ||
[[ ${KEYMAP} = '' ]] ||
[[ $1 = 'beam' ]]; then
echo -ne $cursor_beam
fi
}
zle-line-init() {
echo -ne $cursor_beam
}
zle -N zle-keymap-select
zle -N zle-line-init
}
cursor_mode
```

Fix typo in title, replace abbreviations, minor re-tag (Q is about zsh keybindings in the python interpreter, not vim per se)
