As shown earlier, some commands work on the current selection in a document. In IE, however, you can also let scripting assist with the selection with the aid of the TexTRange object. For example, the following function locates every instance of a string passed as a parameter and turns its text color to red:
The process is iterative. After creating a text range for the entire document body, the function repeatedly looks for a match of the string. Whenever there is a match, the matched word is selected, and the execCommand( ) method invokes the ForeColor command, passing the value red as the color. To continue searching through the range, the range is collapsed after the previously found item, and the selection is removed (by selecting a range of zero length).
