[ENHANCEMENT] Chat: Ctrl Enter Send

[lmtr0]

Problem (one or two sentences)

The current default behavior (Enter = send, Shift+Enter = newline) can lead to accidental prompt submissions and increased physical strain, particularly when writing long or structured prompts.

Context (who is affected and when)

This affects power users who frequently write multiline prompts, especially those using CJK input methods (Chinese, Japanese, Korean), where the Enter key is often used to confirm inline text composition rather than submit content. These users are prone to accidentally sending incomplete prompts, which disrupts workflow and wastes API tokens.

Desired behavior (conceptual, not technical)

Provide a toggle in the settings—ideally under a dedicated "UI" section—to switch between two input modes:

• Option 1: Enter = newline, Shift+Enter / Ctrl+Enter = send
• Option 2: Enter = send, Shift+Enter = newline (current default)

This would allow users to customize the editor behavior according to their typing habits and ergonomic preferences without changing the default globally.

Constraints / preferences (optional)

• Do not introduce hardcoded shortcuts that conflict with common OS or editor defaults (e.g., Ctrl+Y).
• Leverage VS Code's built-in support for customizable keybindings where possible.
• The setting should be opt-in and clearly labeled but not require user education by default.
• Avoid introducing multiple new global shortcuts; instead, consider Alt+Enter as a potential extensible "special action" key for future use (e.g., inserting current file, terminal content), but keep that separate from this change.

I'm exploring a potential fix for this enhancement to add configurable keyboard shortcuts for sending messages. I'll open a PR to share progress.

Hmm, we now have 2 prs for the same issue. :| let the best implementation win

I've opened PR #8557 with my implementation of the configurable keyboard shortcut feature.

The implementation adds a new setting that allows users to toggle between:

• Default mode: Enter sends messages, Shift+Enter creates newlines
• Alternative mode: Enter creates newlines, Shift/Ctrl+Enter sends messages

This should help users who frequently use CJK input methods or prefer traditional text editor behavior. The setting is easily accessible in Settings > UI section.

The PR includes comprehensive tests and maintains backward compatibility. Most CI checks are passing, though there appears to be an issue with the translation check that may need attention from maintainers.

Feedback and suggestions are welcome!
