If `key` is a single character and no modifier keys besides `Shift` are being held down, a `keypress`/`input` event will also generated. The `text` option can be specified to force an input event to be generated.
Modifier keys DO effect [Keyboard.press()](./puppeteer.keyboard.press.md). Holding down `Shift` will type the text in upper case.
