The first step is to download Jing to your computer. Once you download Jing, a small sun icon will appear in the upper right corner of your computer screen. When you hover over the icon, it expands and gives you options to capture, look at your history or view more options.
Once you select your area, you will see a small menu box at the bottom of your selection.
The icons let you capture an image, a recording, redo the selection or cancel the selection. Once you capture the image, you will see another menu box on the side of your selection.
These icons allow you to add arrows, text, frames, highlight, change the color, undo or redo. After your editing is complete, the menu bar at the bottom will allow you to name your image, share it via Screencast.com, save, copy, cancel and customize Jing buttons.
Jing is a great program that allows you to share your screenshot or screencast with your students or co-workers.
TechSmith also offers step by step tutorials to help get you started.
