5555 Make Ctrl+W delete back to whitespace

58By default, `Ctrl+W` deletes the previous word, stopping at punctuation such as `/`. Set [`keybindingFlavor`](/docs/en/settings#available-settings) to `"readline"` to make `Ctrl+W` delete back to the previous whitespace instead, as Bash does. The default value is `"classic"`. Requires Claude Code v2.1.238 or later.

143143### Remap INSERT-mode key sequences
144144 
145The [`vimInsertModeRemaps`](/docs/en/settings#available-settings) setting maps a two-key INSERT-mode sequence to Escape, so a mapping like `jj` returns you to NORMAL mode. Requires Claude Code v2.1.208 or later.

147147The following `~/.claude/settings.json` example turns on vim mode and maps `jj` to Escape:

158158Typing the first character of a sequence inserts it normally. Pressing the second character within one second removes that pending character and switches to NORMAL mode, leaving neither character in your input. After the one-second window, or if a different key follows, both characters stay as literal text, so you can still type a word containing the sequence by pausing between the two keys.

160Claude Code reads this setting from your user settings file, the `--settings` flag, and [managed settings](/docs/en/permissions#managed-settings) only. Entries in a project's `.claude/settings.json` or `.claude/settings.local.json` are ignored, so a checked-out repository can't remap your keystrokes.

323323* Exit with `Escape`, `Backspace`, or `Ctrl+U` on an empty prompt
324324* Pasting text that starts with `!` into an empty prompt enters shell mode automatically, matching typed `!` behavior
325325 
326Claude responds to the command output automatically once it lands in the transcript, so you can run `! npm test` and get an explanation of the failures without a second prompt. The response costs the same as sending a normal prompt. To restore the earlier behavior where the output is added to context without a response, set [`respondToBashCommands`](/docs/en/settings#available-settings) to `false` in `settings.json`. Before v2.1.186, shell mode always added output to context without a response.

381381To disable prompt suggestions entirely, use any of the following:
382382 
383383* Turn off **Prompt suggestions** in `/config`
384* Set [`promptSuggestionEnabled`](/docs/en/settings#available-settings) to `false` in your settings file
384* Set [`promptSuggestionEnabled`](/docs/en/settings-reference#promptsuggestionenabled) to `false` in your settings file
385385* Set the [`CLAUDE_CODE_ENABLE_PROMPT_SUGGESTION`](/docs/en/env-vars) environment variable to `false`, which takes precedence over the setting:
386386 ```bash theme={null}
387387 export CLAUDE_CODE_ENABLE_PROMPT_SUGGESTION=false
388388 ```
389389 
390To turn prompt suggestions off across an organization, set `promptSuggestionEnabled` to `false` in [managed settings](/docs/en/settings#settings-files). Also set `CLAUDE_CODE_ENABLE_PROMPT_SUGGESTION` to `false` under the managed [`env`](/docs/en/settings#environment-variables) key so that users can't re-enable them with their own environment variable.

399399The shortcode must start the input or follow a space, so a `:` inside a word or URL doesn't open suggestions.

401To turn the feature off, set [`emojiCompletionEnabled`](/docs/en/settings#available-settings) to `false` in `settings.json`. This disables both the suggestion popup and the inline replacement.

512512* **Available while Claude is working**: you can run `/btw` even while Claude is processing a response. The side question runs independently and doesn't interrupt the main turn. It sees everything in the conversation so far, except the reply Claude is still writing.
513513* **No tool access**: side questions answer only from what is already in context. Claude can't read files, run commands, or search when answering a side question.
514* **Single response**: there are no follow-up turns in the overlay. To continue the thread, ask another `/btw` question. To continue with full tool access, fork this question and answer into their own session with `f`.

To continue with full tool access in a local session, press `f` to fork this question and answer into a [background subagent](/docs/en/sub-agents#fork-the-current-conversation).
515515* **Low cost**: while the conversation's [prompt cache](/docs/en/prompt-caching) is warm, a side question costs little beyond the answer itself.

526| `Up` / `Down` | Scroll the answer |
527| `Left` / `Right` | Step between this answer and your earlier `/btw` answers. `Left` moves to older answers and `Right` returns toward the current one. Requires Claude Code v2.1.187 or later |

532`/btw` is the inverse of a [subagent](/docs/en/sub-agents): it sees your full conversation but has no tools, while a subagent has full tools but starts with an empty context. Use `/btw` to ask about what Claude already knows from this session; use a subagent to go find out something new.
