Problem Statement

This is related to [https://github.com/anthropics/claude-code/issues/729](url)
Claude doesn't let you set the Enter/ Shift+Enter behavior.
Many people want to press Enter to send a newline, not to send a message. It breaks the flow in long messages.

Proposed Solution

That thread was closed but many people found it annoying.
If anyone is interested there is a workaround here:
