25. A data processing system comprising: a display device; a processor system; a memory coupled to the processor system and to the display device, wherein the processor causes the display device to display a single text input field which, through a first input to the text input field itself, can select between at least a first operation and a second operation and wherein the processor system causes the display device to display a separator within the text input field and wherein a first portion and a second portion of the text input field are separated by the separator and wherein the processor system receives the first input to the single text input field to determine a selected operation which is one of the first operation or the second operation and the processor system receives a text input in the single text input field, the text input being displayable in the entire single text input field and performs the selected operation on the text input wherein the first input comprises receiving a user input in either the first portion or the second portion of the text input field, wherein the first operation is selected if the user input is positioned in the first portion when the user input is received and wherein the second operation is selected if the user input is positioned in the second portion when the user input is received, wherein the first operation is a text search through a first source of data and wherein the second operation is either a file operation or a search operation that is different than the first operation, and wherein in response to the first input, the separator automatically disappears from the text input field and the first portion dominates the entire area of the text input field if the first operation is selected and the second portion dominates the entire area of the text input field if the second operation is selected.
