Kind: Util  
Updated in v16  
Optional

## Usage

Do not guard with `wrHasModifier` first: it counts Shift, so capitals would never arrive.

```angular-ts
import { wrIsPrintableKey } from 'ngwr/utils';

// Type-to-search: ignore arrows, Enter and chords.
@HostListener('keydown', ['$event']) onKey(e: KeyboardEvent) {
  if (wrIsPrintableKey(e)) buffer.push(e.key);
}
```

## API

| Name | Description | Type | Default |
| --- | --- | --- | --- |
| `wrIsPrintableKey(event)` | True for a single printable character with no Ctrl, Cmd or Alt held. Shift is accepted, so capitals arrive. | `(e: KeyboardEvent) => boolean` | `—` |
