+title: Windows Terminal
+description: Configure Shift+Enter for extended keyboard support.
+---
+
+Windows Terminal doesn't send modifier keys with Enter by default. This guide shows how to configure it to send `Shift+Enter` as an escape sequence for apps using extended keyboard protocols.
+
+---
+
+## Prerequisites
+
+You need Windows Terminal v1.0 or later. The latest version from Microsoft Store is recommended.
+
+---
+
+## Define the action
+
+Open your `settings.json` at:
+
+```
+%LOCALAPPDATA%\Packages\Microsoft.WindowsTerminal_8wekyb3d8bbwe\LocalState\settings.json
+```
+
+Add this to the root-level `actions` array:
+
+```json
+"actions": [
+  {
+    "command": {
+      "action": "sendInput",
+      "input": "\u001b[13;2u"
+    },
+    "id": "User.sendInput.ShiftEnterCustom"
+  }
+]
+```
+
+Create the array if it doesn't exist. Ensure proper commas between items.
+
+---
+
+## Bind the key
+
+Add this to the root-level `keybindings` array:
+
+```json
+"keybindings": [
+  {
+    "keys": "shift+enter",
+    "id": "User.sendInput.ShiftEnterCustom"
+  }
+]
+```
+
+Remove any conflicting `shift+enter` entries if present.
+
+---
+
+## Apply changes
+
+Save the file and restart Windows Terminal or open a new tab. Press `Shift+Enter` in OpenCode to insert a newline.
+
+---
+
+## Troubleshooting
+
+If the binding doesn't work:
+
+1. Validate your JSON syntax using a tool like jsonlint.com
+2. Check Settings > Actions in the UI for the binding
+3. Look for conflicting keybindings
+4. Ensure you're using the correct `settings.json` path for your Terminal version (Preview/Canary use different paths)
+
