The keyboard has a number of features built in that are designed to speed up the typing process.
Typing punctuation and numbers can seem like a chore, because it appears that you have to tap the “.?123” button, then the desired character, and then the “ABC” button to return to the normal keyboard. Instead, you can do this action in one finger gesture—tap and hold the “.?123” button, slide your finger to the desired character, and lift your finger. This will type the character and return you to the normal keyboard, all in one action. You can do the same thing for capitalizing letters—tap and hold the shift key, slide to the letter, and lift up. You can also enter a period at the end of a sentence by hitting the space bar twice.
The keyboard has a built-in dictionary that suggests words below what you are typing , which could be either the word that you are in the middle of typing or a correction if you misspelled a word. When you see a suggested word that you want to use, simply tap the space bar and the word will be entered. If it’s incorrect, finishing entering the word. The iPhone will automatically enter the new word into the dictionary.
When typing contractions such as “they’re” and “I’m”, don’t bother typing the apostrophe—in most cases the contraction will be suggested below the word, and you can simply hit the space bar to use it.
