Imagine talking to someone from 30 years ago and telling them, “One day, you will have an all-powerful computer that fits in the palm of your hand that can perform countless tasks and it doesn’t even come with an instruction manual.”

They’d never believe you.

But it’s true. For the most part, when we get a new smartphone, they’re so intuitive, we don’t have to do much searching around to figure out how to use it.

However, that means sometimes cool little features go unnoticed.

Atlanta food blogger Krissy Brierre-Davis recently discovered a new trick on her iPhone that completely blew her mind: if you click and hold anywhere on the keyboard it turns into a trackpad.

“I thought I was an idiot for never having discovered this gem myself,” she told BuzzFeed News. “My mind was blown. Literally. I could never get the cursor to go where I wanted. I’ve even deleted a full sentence just to avoid having to go back and change a mistake in a word.”

Here’s a quick tutorial from tech blogger Lance Ulanoff:

Of course, some nerds out there were quick to point out the feature has been around for over three years.

But most people had no idea about the feature either.
