Shortcodes in Widgets

I had occasion the other day to run a shortcode inside of a text widget. You know shortcodes… we talk about them all the time. They are keywords in [square_brackets] that do something special.

Sometimes they do something really simple like return a string (so you can have a global location to customize some string of text, for example), or they do something more complicated like call a plugin that does something fancy like build a photo gallery.
