Snagit is a screenshot program that can be purchased from TechSmith.  Screenshots are useful and flexible in application for many aspects of instructional design.

Below I have posted a .pdf document of a how-to-guide I developed for Snagit, which I purchased in December 2014.  In December 2014, TechSmith offered a 50% discount for their products for one day.

Enjoy!
