Nope. But if you are using FileMaker 13, you might experiment with setting up a pop over button on top of or behind the field that displays the clicked field in wider format. Just don't try that if you will be using WebDirect to publish the database as there are bugs that will interfere in that context.
IN older versions, a button could open a small window as a modal dialog for the same purpose.
That's a shame :( Not sure why it's not an option, oh well ...
