Getting Started with Key It
Once you have downloaded and installed Key It from an app store tapping its icon brings you to editing the name of the Bible you are starting from.
The next step is to choose the Bible book that you want to keyboard. Just tap on the name of that book in the list, and Key It will create a complete set of chapters in that book and show you a list of them.
Then tap on the chapter you wish to keyboard, and Key It will create a complete set of empty verses for that chapter. Open the existing printed translation you wish to keyboard from and start keyboarding the text of each verse.
At the top left of each verse, Key It displays a label that briefly describes it -- often of the form "Verse 1". If you tap on this label, Key It displays a popup menu of actions that you can choose. For example "Heading Before" which lets you insert a subject heading before the verse, or "Paragraph Before" which lets you insert a paragraph break. These and other commands that may appear on these popup menus allow you to insert many of the additional items that you will see in publications of the Bible.
You can exit from Key It at any time, or switch to a different app on your smartphone, because Key It automatically saves what you have keyboarded as you keyboard. When you return to Key It, you will automatically be taken to the same Book, Chapter, and Verse that you were keyboarding when you left Key It. While keyboarding, you can go back to the list of Chapters in the current book (to choose a different Chapter), or go back further to the list of Books (to choose a different Book).
When you are ready to get the marked up text for a chapter, tap the Export button at the top right of Key It, and Key It will show you the marked up text it has generated. That text can be copied and pasted into an adaptation project in Adapt It Mobile on the same smartphone.
As of version 1.1.x the Export button is renamed USFM, and the display of the USFM has a button named Export that will start Adapt It Mobile and send it the USFM text.
