Shift+Enter submits prompt instead of inserting newline #30544
Description
Description
Pressing Shift+Enter in the terminal UI prompt submits the prompt instead of inserting a newline.
The default keybindings list Shift+Return as an input newline shortcut, so this breaks multiline prompt entry for terminals that report Shift+Enter as Shift+Return.
Plugins
None
OpenCode version
dev branch
Steps to reproduce
- Open the OpenCode terminal UI.
- Type text into the prompt.
- Press Shift+Enter.
Expected behavior
A newline is inserted into the prompt.
Actual behavior
The prompt is submitted.

This is probably happening because your terminal is actually sending a newline to opencode when you press shift+enter. Open a new terminal and run
cat -vand then press shift+enter. If you see a blank line entered then your terminal is actually sending a newline to opencode and opencode never sees the shift+enter. When I do this I see^[[27;2;13~printed to the console.simonklee commentedon Jun 5, 2026

It seems that also tmux is preventing shift+enter from being passed to opencode. In the end I'm just using ctrl+j.

I had the same issue and fixed it by adding this line to my
.tmux.conffile:bind-key -n S-Enter send-keys Escape "[13;2u". Per the comment linked above, this is recognized as a shift+enter sequence by opencode.
