Once your paper or PdF document has been recognized, you may do a number of things with it. To explore your options, first choose the "manage documents" link from the DocuScan Plus main menu. Here, you'll see a list of documents you've created using DocuScan Plus. Choose the one you'd like to work with simply by tabbing to the link and selecting it with the enter key.
Upon doing this, you'll see the document in its entirety, followed by a number of actions you may perform with it. If you want to jump quickly to the first option, press the tab key. This will take you through any links present in the document itself, and then your focus will then land on the first DocuScan Plus option, which is "email a document."
