Where is the atl key on the phone keyboard?

If the mobile phone is not a pen key, but a general smart phone, there is generally no atl key on the keyboard.

But if it's an Apple phone, change the keyboard to 26 input method and choose English. Then click on the space bar below, hold it down for about two seconds before releasing it, which is equivalent to the function of alt key.

Alt key is also called Alternate shift key, change key and replacement key, because it is the abbreviation of the English word "alternate" (exchange, replacement), and is used in combination with other keys in most cases. Without a mouse, you can easily open the menu of the software with the "Alt" key.
