Adding a "quote" button to jwysiwyg

I'm trying to add a "quote" button to jwysiwyg, but I'm having a problem... My code for the button is like:

quote: {
  visible: true,
  tags: ['blockquote'],
  command: "FormatBlock",
  "arguments": ($.browser.msie || $.browser.safari) ? "<blockquote>" : "blockquote",
}

and it works (at least in Firefox), but when I press the button and the blockquote appears, I can't find a way to move the cursor outside that block, and everything I type afterwards en开发者_Python百科ds up as quoted.

What could I try?

The jwysiwyg source code has an example of how to do this:
