# Find a key

`GET /v1/keys/{key}` tells you which sizes keep a key. Sizes without it usually reach it through an Fn layer.

## Key names

Use a key or a group, with hyphens or URL-encoded spaces: `delete`, `insert`, `home`, `end`, `page-up`, `page-down`, `print-screen`, `f1` to `f12`, `esc`, `backtick`, `right-ctrl`, `menu`, `arrow-keys`, `f-keys`, `navigation-keys` or `numpad`. Add `?iso=true` for UK/EU layouts.

## Example

```bash
curl "https://api.hlplanet.com/v1/keys/f5"
```

```json
{
  "key": "F5",
  "codes": [
    "F5"
  ],
  "layout": "ANSI",
  "sizes": [
    {
