1. A computer-implemented method for designating identifier-associated sentences, the computer-implemented method comprising: distinguishing, by a computer system including an electronic processor and at least one operatively associated memory, a plurality of sentences of a data source; storing said plurality of distinguished sentences in said memory; associating each of said plurality of distinguished sentences with an identifier, said identifier being unique to each sentence, resulting in a plurality of corresponding identifier-associated sentences; storing said plurality of identifier-associated sentences in said memory; receiving a user search query; displaying, in response to the user search query, a first identifier-associated sentence, the first identifier-associated sentence containing a response to the search result; displaying, in response to the user search query, a second identifier-associated sentence, the second identifier-associated sentence also containing a response to the search result; displaying a plurality of navigation controls, each control associated with a displayed identifier-associated sentence; displaying, in response to receiving a first user navigation request associated with the first identifier-associated sentence, a previously undisplayed third identifier-associated sentence, the third identifier associated sentence being the identifier associated sentence immediately succeeding, in the data source, the first identifier-associated sentence and, upon its initial display, the third identifier-associated sentence displayed simultaneously with the first and second identifier-associated sentences; displaying, in response to receiving a second user navigation request associated with the second identifier-associated sentence, a previously undisplayed fourth identifier-associated sentence, the fourth identifier-associated sentence being the identifier associated sentence immediately succeeding, in the data source, the second identifier-associated sentence and, upon its initial display, the fourth identifier-associated sentence displayed simultaneously with the first, second, and third identifier-associated sentences; and incrementally displaying, in response to a user navigation request, one or more previously undisplayed identifier-associated sentences which are further associated with one of the displayed identifier-associated sentences based on a defined relation, wherein an additional identifier-associated sentence is displayed in response to each additional user navigation request, the further identifier-associated sentences displayed simultaneously with the previously displayed identifier-associated sentences.
