How to emulate TAB key press in Puppeteer

In order to emulate a tab key press in Puppeteer, use

await page.keyboard.press("Tab");

Full example:

// Minimal puppeteer example
const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch({defaultViewport: {width: 1920, height: 1080}});
  const page = await browser.newPage();
  await page.goto('https://techoverflow.net', {waitUntil: 'domcontentloaded'});
  // Press tab 10 times (effectively scrolls down on techoverflow.net)
  for (let i = 0; i < 10; i++) {
      await page.keyboard.press("Tab");
  }
  // Screenshot to verify result
  await page.screenshot({path: 'screenshot.png'});
  // Cleanup
  await browser.close();
})();
