<P> A text widget implements a basic GUI based text editor.
Manipulation of the text is not limited to users, your scripts can also do it.

<P> Text widgets have a mechanism for identifying subsets of the text. This is
valuable because you can assign different fonts, colors, and bindings to these
subsets as well as perform editing operations on them.  

<P> Although primarily oriented towards textual material, text widgets can also
contain other widgets.
