+## Ctrl C Workaround
+
+There is currently an issue with `ctrl+c` not stopping a running process in the integrated terminal. We have filed an issue upstream and are tracking [here](https://github.com/microsoft/vscode/issues/114009). As a temporary workaround, it works if you manually define the shortcut like so:
+
+1. Open Command Palette
+2. Look for "Preferences: Open Keyboard Shortcuts (JSON)"
+3. Add this:
+
+```json
+{
+  "key": "ctrl+c",
+  "command": "workbench.action.terminal.sendSequence",
+  "args": {
+    "text": "\u0003"
+  },
+  "when": "terminalFocus"
+}
+```
