Snagit has been a part of my tool box of applications that I use for many years. I am not sure how I would work if I didn’t have it available to me. Some of the features that I like include scrolling back through screen grabs to reuse an image, editing and image either by cropping or creating special effects. This is great for inserting an image into a quote or a document quickly with little work.
TechSmith’s library of tutorials are especially helpful to get you up and running or get a quick refresher on how a particular part of the program works. They have both written and video tutorials to draw on for all of their programs so don’t be shy accessing them since they are free for your use. http://www.techsmith.com/tutorial-snagit-current.html
