Plugin to select jQuery text editor style?

Question

I'm trying to make sure jQuery is used to simulate the behavior of the text highlighting functions that you see in a typical text editor, except that instead of highlighting the text, I want to select a few lines of <div>s. However, so far the only "select" plugins I have found for jQuery are based on a rectangular lasso model. In particular, I am using the selectable jQueryUI plugin. To see what I'm talking about, consider the following 2 images:

, :

var sR = $('#selectable').selectableRange({
    /* Alternatively, you could overwrite default options
    classname: 'active',
    log: false,
    logElement: $('#log'),
    nodename: 'LI'*/
});

// Initialize the selectable so it works
sR.init();

// You can always change options like this:
$('#logOnOff').click(function(){
    // Toggle log
    sR.options.log = (sR.options.log) ? false : true;
});

// Also you can use this methods:
// sR.deselect()
// sR.destroy()
// sR.getSelectedItems()

$(function() {
    var selectableLi = $('#selectable li');
    selectableLi.mousedown(function(){
        var startIndex, endIndex, mouseUpOnLi = false;

        // When dragging starts, remove classes active and hover
        selectableLi.removeClass('active hover');

        // Give the element where dragging starts a class
        $(this).addClass('active');

        // Save the start index
        startIndex = $(this).index();

        // Bind mouse up event 
        selectableLi.bind('mouseup', function(){

            // Mouse up is on a li-element
            mouseUpOnLi = true;
            $(this).addClass('active');

            // Remove the events for mouseup, mouseover and mouseout
            selectableLi.unbind('mouseup mouseover mouseout');

            // Store the end index
            endIndex = $(this).index();

            // Swap values if endIndex < startindex
            if(endIndex < startIndex){
                var tmp = startIndex;
                startIndex = endIndex;
                endIndex = tmp;                 
            }

            // Give the selected elements a colour
            for(i=startIndex; i<=endIndex; i++){
                $(selectableLi[i]).addClass('active');
            }

        }).bind('mouseover', function(){
            // Give elements a hover class when hovering
            $(this).addClass('hover');
        }).bind('mouseout', function(){
            // Remove the hover class when mouse moves out the li
            $(this).removeClass('hover');
        });

        $(document).bind('mouseup', function(e){
            // When mouse up is outside a li-element
            if(!mouseUpOnLi){
                selectableLi.removeClass('active');
            }
            $(this).unbind('mouseup');
        });
    }).attr("unselectable","on").css("MozUserSelect","none").bind("selectstart",function(){return false});
});

, :

var selectableLi;

function colourSelected(a, b, Class){
    selectableLi.removeClass(Class);
    // Swap values if a > b
    if(a > b){
        var tmp = a;
        a = b;
        b = tmp;                    
    }

    // Give the selected elements a colour
    for(i=a; i<=b; i++){
        $(selectableLi[i]).addClass(Class);
    }       
}

$(function() {
    selectableLi = $('#selectable li');
    selectableLi.mousedown(function(){
        var startIndex, endIndex, mouseUpOnLi = false;

        // When dragging starts, remove classes active and hover
        selectableLi.removeClass('active hover');

        // Give the element where dragging starts a class
        $(this).addClass('active');

        // Save the start index
        startIndex = $(this).index();

        // Bind mouse up event 
        selectableLi.bind('mouseup', function(){

            // Mouse up is on a li-element
            mouseUpOnLi = true;
            $(this).addClass('active');

            // Remove the events for mouseup, mouseover and mouseout
            selectableLi.unbind('mouseup mouseover mouseout');

            colourSelected(startIndex, $(this).index(), 'active');

        }).bind('mouseover mouseout', function(){
            // Give elements a hover class when hovering
            colourSelected(startIndex, $(this).index(), 'hover');
        });

        $(document).bind('mouseup', function(e){

            if(!mouseUpOnLi){
