fix(code): preserve `Ctrl+D` deletion in non-empty input by wbbradley · Pull Request #4626 · langchain-ai/deepagents

Will Bradley (wbbradley) · 2026-07-10T05:05:40Z

Ctrl+D now deletes the character to the right in a non-empty prompt and only exits from an empty prompt.

A priority app binding intercepted Ctrl+D before the focused chat text area could apply its standard delete-right behavior. Delegate Ctrl+D to the focused text area while a draft exists, and retain quit behavior for an empty prompt and existing modal flows.

Just a couple new lines for readability, nbd either way. Thanks for submitting this!

Follow-up to #4626. `Ctrl+D` now quits Deep Agents Code when the cursor is at the end of the prompt, including when the prompt contains text. It continues to delete selected text or content to the right of the cursor. --- After #4626, `Ctrl+D` preserves its delete-right behavior whenever the prompt contains a draft. At the end of a non-empty prompt, however, there is nothing to delete and the key does nothing. Treat the end of the prompt like the empty-prompt case: `Ctrl+D` quits when there is no selection and no content to the right. It continues to delete selected text, delete the next character, or join multiline input when the cursor is not at the true end of the prompt.
