13. A server device, comprising: a processor; a computer-readable memory device including a document identification index and a document action map; and a network connection that receives from a network a sequence of characters optically or acoustically captured from a rendered document by a capture device and transmitted to the network connection via the network, wherein the processor identifies, from the document identification index, a document that that includes a sequence of characters that matches the captured sequence of characters, wherein the processor identifies, from the document identification index, a position, within the identified document, of the sequence of characters that matches the captured sequence of characters, and wherein the processor identifies, from the document action map, a word, phrase or symbol that is within the sequence of characters at the identified position within the identified document and that is associated with an action.
