For those using `keyCode` in their codebase, we recommend converting them to their kebab-cased named equivalents.

The keys for some punctuation marks can just be included literally. e.g. For the `,` key:

```html
<input v-on:keypress.,="commaPress">
```

Limitations of the syntax prevent certain characters from being matched, such as `"`, `'`, `/`, `=`, `>`, and `.`. For those characters you should check `event.key` inside the listener instead.
