Describe multiple windows, input events, lifecycle, and capabilities with typed records.

```yh
external thing nativeKeyboardRecord
```

- text windowId: Stores window id as text.
- int sequence: Stores sequence as int.
- int physicalCode: Stores physical code as int.
- text logicalKey: Stores logical key as text.
- text modifiers: Stores modifiers as text.
- bool repeated: Stores repeated as bool.
- int timestampMicroseconds: Stores timestamp microseconds as int.
- text deviceId: Stores device id as text.
- text source: Stores source as text.
- bool committedText: Stores committed text as bool.
- nativeKeyboardRecord(text windowId, int sequence, int physicalCode, text logicalKey, text modifiers, bool repeated, int timestampMicroseconds, text deviceId, text source): Native keyboard record.
- Validate() returns text: Validate.
- Describe() returns text: Describe.

## Use nativeKeyboardRecord

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using window.multi

// Describe multiple windows, input events, lifecycle, and capabilities with typed records.
nativeKeyboardRecord sample = nativeKeyboardRecord("window Id", 1, 1, "logical Key", "modifiers", true, 1, "device Id", "example")
Console.Log(Text.From(sample.windowId))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.window_multi__nativekeyboardrecord"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "window.multi"
version = "0.1.0"
path = "../../../yeho/packages/window/multi"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/window.multi--nativeKeyboardRecord/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## nativeKeyboardRecord.Validate

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using window.multi

// Validate.
nativeKeyboardRecord instance = nativeKeyboardRecord("window Id", 1, 1, "logical Key", "modifiers", true, 1, "device Id", "example")
text result = instance.Validate()
Console.Log(Text.From(result))

```

[app]

```


## nativeKeyboardRecord.Describe

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using window.multi

// Describe.

text result = instance.Describe()
Console.Log(Text.From(result))

```

```


Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
