Why should you register for two or more keyboards?-Why can't you hear iPhone now?

IOS uses a virtual keyboard (software keyboard) drawn on the screen to enter characters. Although it is possible to use an external keyboard connected through Bluetooth, it is almost always a person who uses a software keyboard.

The software keyboard usually registers multiple keyboards depending on the language and input method used for input. Since you must log in at least 1, it cannot be set to zero, but if you use it in a Japanese environment, there should be a large number of users who log in to "Japanese" or "Japanese-Roman characters", "picture text" and so on.

When you register multiple software keyboards, you will switch according to the situation, and you will click the Earth button displayed in the lower left corner of the screen. If you have only one keyboard registered, the Earth button will not be displayed, but if you do not need to switch the keyboard, this seems good.

However, that earth button has another important function in addition to switching software keyboards. It is "turn on / off one-handed keyboard and switch display position".

The one-handed keyboard added in IOS 11 is a function that displays the software keyboard on the left or right side of the screen. The top of the key will become smaller, but because you don't need to hold out your finger when holding the iPhone in one hand, there should be a lot of people you like.
