How can I share the extracted text?

You can share the extracted text from listing screen as well as from text detail screen.

If you want to share from the listing screen, you just need to long tap on the item and a Forward icon will appear at the top right corner of the list along with a Delete icon. You have to tap on the forward icon and select any local device app with which you want to share.

If you want to share the text directly from the text edit screen, you have to tap on the Forward icon which is given at the top right corner of this screen too.
