How does readline-sync.keyIn work?

readline-sync.keyIn is a synchronous method of the readline-sync module in Node.js that waits for user input from the terminal and returns the input as a string or a number, based on the options provided, until a specific key is pressed.

The `query` is handled the same as that of the [`question`](#basic_methods-question) method.

For example:

```js
menuId = readlineSync.keyIn('Hit 1...5 key: ', {limit: '$<1-5>'});
```

### <a name="basic_methods-setdefaultoptions"></a>`setDefaultOptions`

const readlineSync = require("readline-sync");
const choices = ["rock", "paper", "scissors"];
const index = readlineSync.keyInSelect(choices, "What's your choice?");
console.log(`You chose ${choices[index]}`);

In this example, the keyInSelect function is used to prompt the user to select a choice from the provided array of options, and the user's choice is returned as the index of the selected option. The index is then used to retrieve the corresponding value from the array.
