Dispatches a keydown event.
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.
If key is a modifier key, Shift, Meta, Control, or Alt, subsequent key presses will be sent with that modifier active. To release the modifier key, use keyboard.up.
After the key is pressed once, subsequent calls to keyboard.down will have repeat set to true. To release the key, use keyboard.up.
NOTE Modifier keys DO influence keyboard.down. Holding down Shift will type the text in upper case.

Keyboard provides an api for managing a virtual keyboard. The high level api is keyboard.type, which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page.
For finer control, you can use keyboard.down, keyboard.up, and keyboard.sendCharacter to manually fire events as if they were generated from a real keyboard.
An example of holding down Shift in order to select and delete some text:
await page.keyboard.type('Hello World!'); await page.keyboard.press('ArrowLeft'); await page.keyboard.down('Shift'); for (let i = 0; i < ' World'.length; i++) await page.keyboard.press('ArrowLeft'); await page.keyboard.up('Shift'); await page.keyboard.press('Backspace'); // Result text will end up saying 'Hello!'An example of pressing A
await page.keyboard.down('Shift'); await page.keyboard.press('KeyA'); await page.keyboard.up('Shift');
