However, I would like to have the equivalent of a highlight pen, where the user selects a highlight color and then drags across the text. I cache the current selection highlight color, then change the selection highlight to the chosen color. The intent (not completely implemented yet) is, on mouseUp, to then set the background color, deselect the text, and restore normal highlighting. I have created an augmented iBeam cursor (including a color patch), but have had difficulty getting the text cursor to switch from the iBeam to mine.

>> Marked text in Cocoa is mainly used by input methods. Primarily with languages that have more glyphs than you would have on a keyboard and input is done in a form that is analyzed and is provided a set of conversion options. a range of input text that is not yet committed is highlighted and commonly sub ranges can be selected and converted. When conversions are selected and finalized text is unmarked and ready for committing.
