This is how voca works:

When you select text on a PDF or webpage, click the *Share* button to access three options:

1. **Read Now**: Instantly start reading the text aloud, with the Voca UI highlighting spoken words in real time.

2. **Queue**: Add the text to a background queue for later reading, similar to bookmarking.

3. **Create MP3**: Generate an audio file in the background and optionally send it to your podcast app queue.
