For the need to often input some long text, such as address, ID number and so on, we can quickly input through the input code.
The setting method is as follows: open system preference Settings – keyboard – text, click on the lower left corner of the plus sign, and then in the input code column below the input “address” pinyin at the beginning of the first letter: DZ, and then in the phrase column below input specific address;
So when you want to type in your address, you just type “DZ” and the address pops up for you to choose, and the system syncs it to your iPhone via iCloud, so you can quickly type it in on your iPhone.
