I somehow randomly discovered this trick a long time ago, could be a few years, and I’ve just come to rely on it all the time. I wondered if many people knew about it, hence this post.
If you’re browsing a list, typically Safari web browser, Twitter timeline, Facebook, anything that has a scrollable list, you can jump straight back to the top with a gentle double tap somewhere on the navigation bar. I use it so often that I don’t even know when I first started. It could be a time saver for those who browse back and forth through a long list of items.
Caveat: if the app you are using has buttons on the navigation bar, you want to avoid tapping those. But I found that any free space on that navigation bar will work the same way.
