Shift+Enter line break not working in Warp terminal (only Ctrl+J works)

[realsamrat]

Description

Environment

• OpenCode version: 1.0.180
• Terminal: Warp
• OS: macOS

Problem

Shift+Enter does not insert a line break in the input when running OpenCode inside the Warp terminal. The expected behavior is that Shift+Enter should create a new line, allowing multi-line input before submitting.
Current Behavior

• Pressing Shift+Enter does nothing (no line break inserted)
• Only Ctrl+J works as a workaround for inserting line breaks

Expected Behavior

Shift+Enter should insert a line break in the input field, consistent with behavior in other terminals.

Workaround

Using Ctrl+J instead of Shift+Enter successfully inserts a line break.

Additional Context

This may be related to how Warp handles key bindings or how OpenCode captures keyboard input. Other terminals may not have this issue.

OpenCode version

Steps to reproduce

1. Open Warp terminal
2. Run OpenCode (version 1.0.180)
3. Start typing a message
4. Press Shift+Enter to insert a line break
5. Observe: nothing happens

Warp does not support modifyOtherKeys or kitty keyboard protocol. Warp will only work when it supports it, see Warp issues like these:

warpdotdev/warp#2037
warpdotdev/warp#2528

The only thing you can do is adding a custom keybinding for shift+enter to send \n. See something like this: https://github.com/warpdotdev/keysets/tree/main
