Use tool bar button to insert tags at beginning and end of selected text

[John]

On a custom toolbar button click I would like to insert a start html tag at begining of  selected content and and an close tag at the end of the selection.

There is a help on inserting HTML tag at the beginning of the selection, the problem is inserted the close tag at the end of the selection

for example a user selcts some text in content area;
Telerik.Web.UI.Editor.CommandList["MyTestButton"] = function(commandName, editor, args)
{
   editor.pasteHtml('<TagBegin>');

       /*some way to find end of selection ???*/

   editor.pastHtml('<TagEnd>');
 
};

Thanks in advanced
