Tap on key 123 to switch to a familiar phone-style numeric keyboard.

Tap again to switch back.

Using the numeric keyboard, you can enter all numbers, as well as all special characters—not to mention some nifty mathematical signs you enter by drawing a circle on some number keys!

You can also see and enter the special characters from the main letter keyboard. See special_characters_string section.

In settings_string you can choose how the number keyboard should change back to the letter keyboard: You can check the box to make this automatic, upon entering a space, or you can leave it unchecked and tap on the key ABC to switch back to letters again.

Finally you can even enter numbers from the main letter keyboards, without changing to the number keyboard. To do this, please see advanced_options_string under how_to_string
