For example: + +```zsh +MODE_INDICATOR="%F{white}+%f" +INSERT_MODE_INDICATOR="%F{yellow}+%f" +``` + +### Adding mode indicators to your prompt + +`Vi-mode` by default will add mode indicators to `RPROMPT` **unless** that is defined by +a preceding plugin. + +If `PROMPT` or `RPROMPT` is not defined to your liking, you can add mode info manually. The `vi_mode_prompt_info` function is available to insert mode indicator information. + +Here are some examples: + +```bash +source $ZSH/oh-my-zsh.sh + +PROMPT="$PROMPT\$(vi_mode_prompt_info)" +RPROMPT="\$(vi_mode_prompt_info)$RPROMPT" +``` + +Note the `\$` here, which importantly prevents interpolation at the time of defining, but allows it to be executed for each prompt update event. + +## Cursor Styles + +You can control the cursor style used in each active vim mode by changing the values of the following variables. + +```zsh +# defaults +VI_MODE_CURSOR_NORMAL=2 +VI_MODE_CURSOR_VISUAL=6 +VI_MODE_CURSOR_INSERT=6 +VI_MODE_CURSOR_OPPEND=0 +``` + +- 0, 1 - Blinking block +- 2 - Solid block +- 3 - Blinking underline +- 4 - Solid underline +- 5 - Blinking line +- 6 - Solid line + +## Key bindings + +Use `ESC` or `CTRL-[` to enter `Normal mode`. + +NOTE: some of these key bindings are set by zsh by default when using a vi-mode keymap. + +### History + +- `ctrl-p` : Previous command in history +- `ctrl-n` : Next command in history +- `/` : Search backward in history +- `n` : Repeat the last `/` + +### Vim edition + +- `vv` : Edit current command line in Vim + +NOTE: this used to be bound to `v`.

Contents can then be put back using paste commands +(`P`, `p`). + +## Text objects + +Standard text objects are supported with `i` ("inside") and `a` ("around"), e.g., for words; thus, you can select the word the cursor is in with `viw`, or delete the current word, including surrounding spaces, with `daw`. + +For other text objects, you can rely on the built-in functionality of Zsh and enable it accordingly. +For example, for quoted strings, you can copy the commented snippet of <https://sourceforge.net/p/zsh/code/ci/master/tree/Functions/Zle/select-quoted>: place this in your `.zsrhc` file, e.g., after sourcing oh-my-zsh: + +```sh +autoload -U select-quoted +zle -N select-quoted +for m in visual viopp; do + for c in {a,i}{\',\",\`}; do + bindkey -M $m $c select-quoted + done +done +``` + +Now, in normal mode, you can select everything inside a double-quoted string with `vi"`. +Note that this works even if you're not already inside a quoted string. +For example, you can replace everything inside a single-quoted string in the current line, from wherever the cursor is, with `ci'`. + +## Known issues + +### Low `$KEYTIMEOUT` + +A low `$KEYTIMEOUT` value (< 15) means that key bindings that need multiple characters, +like `vv`, will be very difficult to trigger. `$KEYTIMEOUT` controls the number of +milliseconds that must pass before a key press is read and the appropriate key binding +is triggered. For multi-character key bindings, the key presses need to happen before +the timeout is reached, so on low timeouts the key press happens too slow, and therefore +another key binding is triggered. + +We recommend either setting `$KEYTIMEOUT` to a higher value, or remapping the key bindings +that you want to trigger to a keyboard sequence. For example: + +```zsh +bindkey -M vicmd 'V' edit-command-line # this remaps `vv` to `V` (but overrides `visual-mode`) +``` |
