If you have a CCLI SongSelect account, you can easily import lyrics into Presenter.
First, you'll need to connect SongSelect to Presenter. Navigate to "Settings" by clicking the gear icon in the upper right corner of Presenter. Then select "Connections" from the left-hand menu. Here, you can connect to SongSelect using an active SongSelect email and password.
After your connection has been established, click the "Songs" button in the command toolbar at the top of the Presenter app to start importing.
You can use the "Filter" on the left to search your existing song library, as well as SongSelect's library for new imports. (At this time, you will not be able to import from SongSelect through the Cue editing window, as it will only let you select from songs that are already in your library.)
If the song you want is not already in your library, you can find the song from the SongSelect results. Click the play button next to the song name to hear a snippet of the song, and/or click on the song itself to look at the lyrics to make sure you've found the right song.
When you've found the right song, adjust the Import Options on the right of the song preview pane and click "Import." The song is now added to your library. From here, you can either exit this screen by clicking the "x" in the top right corner, or you can "Import Again" (helpful for if you do various arrangements of the same song), "Edit" the song file you just imported, or "Add to Cue List" to add it to the Cue List you currently have open.
Note: Importing from SongSelect requires a paid SongSelect subscription.
