```
selection.Selection.filter(predicate: : (value: Model, index: number, values: readonly Model[]) => value is Narrowed, thisArg: : unknown) -> Selection<Narrowed>
```

Keep the members `predicate` accepts.

For a question that has to run code. When the question can be expressed as
criteria, `where` says the same thing as data — which can be logged, sent
to another process, or stored.

## Example

```ts
snapshot.panes.filter((entry) => entry.currentCommand?.startsWith("v") === true);
```
