Blink supports signature help, automatically triggered when typing trigger characters, defined by the LSP, such as `(` for `lua`. The menu will be updated when pressing a retrigger character, such as `,`. Due to it being experimental, this feature is opt-in.

```lua
signature = { enabled = true }
```
