 - command: On the command line, you let your shell split the commands into arguments. In the JSON format, you need to do it yourself. For example, if you had `run-pty % npm run frontend` on the command line, the JSON version of it is `["npm", "run", "frontend"]`. And `run-pty % echo 'hello world'` would be `["echo", "hello world"]`.

 - defaultStatus: This lets you replace 🟢 with a custom status indicator at startup (before your command has written anything). The value works like for `status`.
 
+- killAllSequence: When you use “kill all” run-pty sends <kbd>ctrl+c</kbd> to all commands. However, not all commands exit when you do that. In such cases, you can use `killAllSequence` to specify what sequence of characters to the command to make it exit.
+
 Instead of JSON, you can also use [NDJSON] – one JSON object per line (blank lines are OK, too). This is handy if you generate the file on the fly using some primitive scripting language.
