TextHelp: One of the New Add-Ons in GDocs

This week, a powerful new feature appeared on Google Docs.  You and your students can now run little sub-programs called ‘scripts’ on your Documents. These scripts can be found in the new ‘Add-ons’  button located in the main ribbon:

There are tools in there for making bibliographies, adding charts, making labels, flowcharts/mindmaps, tables of contents, and even for writing music.  The one that caught my eye is the highlighting tool called TextHelp.

Students can highlight parts of a text in different colors, and then this script will collect the different colored highlights together in a new document. Check out this page of suggestions on how to use this in the classroom.
How else could this be used with students?
