Describe the enhancement you want to request

Hi,

In Claude Code, when an edit, shell command, etc., requires approval, you can tap Shift while the cursor is on Yes or No to approve/reject the edit and provide additional comments/context before the agent continues.

For example:
Shift+Yes: ", but you forgot to use the helper function we defined in..."

The current equivalent flow in OpenCode would be to reject the edit and provide the feedback in a separate prompt, which costs the LLM having to regenerate the edit.

Claude Code's Shift+Yes interaction feels very natural, and it would be great to have an equivalent workflow in OpenCode. My sincerest thanks to the OpenCode team.
