What is the code that determines the current selection?

Hi @dublove have a look at this:

(function () {

    var doc = app.activeDocument,
        item = doc.selection[0];

    if (!item)
        alert('You have nothing selected.');

    if ('Image' === item.constructor.name)
        alert('You have selected a graphic.');

    if (
        item.hasOwnProperty('graphics')
        && 1 === item.graphics.length
    )
        alert('You have selected an image frame.');

    if ('TextFrame' === item.constructor.name)
        alert('You have selected a text frame.');

    if (
        item.hasOwnProperty('texts')
        && 1 === item.texts.length
    )
        alert('You have selected something with text.');

    if ('InsertionPoint' === item.constructor.name)
        alert('Your cursor is in the text');

    if (
        'InsertionPoint' === item.constructor.name
        && 'Cell' === item.parent.constructor.name
    )
        alert('Your cursor is in a table row.');

    if (
        // table cell selections are always 'Cell'
        'Cell' === item.constructor.name
        // two rows
        && 2 === item.rows.length
        // rows are first and second
        && 0 === item.rows[0].index
        && 1 === item.rows[1].index
        // both whole rows are selected
        && item.cells.length == item.rows.everyItem().cells.length
    )
        alert('You have selected the top two rows of the table.');

})();
