It has become apparent that it has not been known to many, although it has been present in iPhone phones for three years, and the way you write messages on your phone has changed.
Although this feature has been available on iPhone phones for three years, the feature of the phone keypad recently discovered by thousands of Apple users after Chris Pierre "discovered" on Twitter.
"How did you guys tell me about the trick of this iPhone? I feel deceived," said the girl, along with a screen image of the distance button on an iPhone keyboard while moving the cursor.
"If you click the space button and continue clicking, you can move the pointer instead of trying to pull the same pointer with your thick thumb."
This tweet, which has since received more than 31 thousand admiration, has prompted people to experience this trick themselves.
"This information is changing the course of life," one of them wrote in exaggeration. "I was amazed."
One of those traumatized by this feature was New York Times Tech News Editor Mike Isaac, who wrote an eulogy: "This has just changed my whole life."
"You can not only do this, but when you move the cursor, you can press down a little harder and you can shade a word or phrase," wrote another person.
We tried on Al Jazeera Net to try this shading issue and once succeeded and failed several times, and may need some flexibility before mastering it.
Some users have confirmed that this feature is not new, and it has existed since the days of the iPhone 6S, which was launched in 2015, and wrote "One word: manual of use".
Did you know this feature exists in your iPhone?
