How do I make the keyboard disappear?

When you’re writing a Journal entry, the keyboard on your iPhone or iPad will cover up the bottom toolbar, which includes the button to publish the entry. You will need to hide the keyboard before you can tap that button.

On iPads, there is a key at the bottom right corner of the keyboard that will do this for you.

On both iPads and iPhones, you can tap the blank white space between the keyboard and the box where you write your Journal entry, to force the keyboard to hide.
