causing a different portion of the document including a second subset of the plurality of selectable items in the set to be presented on the display, wherein said second subset of the plurality of selectable items is different from the first subset of the plurality of selectable items.

7. The method of claim 2 , further comprising:

in response to receiving, via the audio input device, a fifth voice command indicating that said different one of the selectable items is to be selected, causing information associated with said different one of the selectable items to be presented on the display, wherein the information associated with said different one of the selectable items corresponds to the second navigational level of the information hierarchy.

8. The method of claim 1 , wherein the plurality of selectable items comprise hyperlinks.

9. The method of claim 1 , wherein causing one of the selectable items in the plurality of selectable items to be displayed differently from the other selectable items comprises highlighting said one of the selectable items in the plurality of selectable items.

10. The method of claim 1 , wherein the plurality of selectable items comprise one or more of form fields, pull-down menus, scroll boxes, text boxes, form buttons, radio buttons, check boxes, or data fields.

11. The method of claim 1 , wherein the plurality of selectable items are included in a web page to be presented on the display and wherein causing information associated with the accentuated selectable item to be presented on the display comprises transmitting a request to retrieve a linked web page and, in response to receiving data corresponding to the linked web page, causing the linked web page to be presented on the display.

12. The method of claim 1 , wherein the first and second voice commands are different.

13. The method of claim 1 , wherein causing identifying indicia to be presented on the display in association with the plurality of selectable items comprises overlaying an identifying indicium over each of the plurality of selectable items.

14. The method of claim 1 , wherein a subset of the plurality of selectable items including multiple selectable items are presented on the display in an identical manner and each of the identifying indicia associated with the subset of the plurality of selectable items are presented on the display in a manner different from the other identifying indicia associated with the subset of the plurality of selectable items.

15. The method of claim 1 , wherein the identifying indicia comprise one or more of letters, numbers, or symbols.

16. The method of claim 1 , wherein the image tag is a hypertext markup language (HTML) image tag and the text included with the image tag is text of an alt attribute of the HTML image tag.

17. A mobile communication device comprising:

a display;

an audio input device; and

a processor in operative association with the display and the audio input device, the processor configured to:

cause a plurality of selectable items to be presented on the display, wherein the plurality of selectable items are associated with a first navigational level of an information hierarchy;

in response to receiving, via the audio input device, a first voice command indicating that one of the plurality of selectable items is to be selected, causing one of the selectable items in the plurality of selectable items to be displayed differently from the other selectable items to thereby form an accentuated selectable item;

in response to receiving, via the audio input device, a second voice command indicating that the accentuated selectable item is to be selected, causing information associated with the accentuated selectable item to be presented on the display, wherein the information associated with the accentuated selectable item corresponds to a second navigational level of the information hierarchy;

generate identifying indicia associated with the plurality of selectable items based on the first navigational level of the information hierarchy;

cause the identifying indicia to be presented on the display in association with the plurality of selectable items, wherein each identifying indicium corresponds to one of the plurality of selectable items; and

in response to receiving, via the audio input device, a third voice command specifying one of the identifying indicia, cause information associated with the selectable item corresponding to said specified one of the identifying indicia to be presented on the display;

wherein the identifying indicia comprise text corresponding to text included with an image tag in the information hierarchy associated with a displayed image that is one of the plurality of selectable items.

18. The mobile communication device of claim 17 , further comprising:

a communication module configured to communicate via a communication network, wherein causing information associated with the accentuated selectable item to be presented on the display comprises transmitting to a server via the communication network a request to retrieve a linked web page and, in response to receiving from the server via the communication network data corresponding to the linked web page, causing the linked web page to be presented on the display.

19. A non-transitory computer-readable medium having instructions stored thereon, the instructions comprising:

instructions for causing a plurality of selectable items to be presented on a display associated with a mobile communication device, wherein the plurality of selectable items are associated with a first navigational level of an information hierarchy;

instructions for, in response to receiving, via an audio input device associated with the mobile communication device, a first voice command indicating that one of the plurality of selectable items is to be selected, causing one of the selectable items in the plurality of selectable items to be displayed differently from the other selectable items to thereby form an accentuated selectable item;

instructions for, in response to receiving, via the audio input device, a second voice command indicating that the accentuated selectable item is to be selected, causing information associated with the accentuated selectable item to be presented on the display, wherein the information associated with the accentuated selectable item corresponds to a second navigational level of the information hierarchy;

instructions for generating, by the mobile communication device, identifying indicia associated with the plurality of selectable items based on the first navigational level of the information hierarchy;

instructions for causing the identifying indicia to be presented on the display in association with the plurality of selectable items, wherein each identifying indicium corresponds to one of the plurality of selectable items and the identifying indicia comprise text corresponding to text included with an image tag in the information hierarchy associated with a displayed image that is one of the plurality of selectable items; and
