When you release your mouse several other options appear on the screen. Left to right they are: capture image, capture video, redo selection, and cancel. The size of your screen capture is also shown.
When adding text to the screen capture there is a fairly large selection of font choices. Text size can be made smaller or larger. There are nine basic colors for the tools or you can customize the color. Each item added to the image can be sized using any of the four corners. Delete an item by using the undo arrow.
When selecting the save button your completed screen capture is downloaded to your computer and a URL link is placed on your clipboard. If I wish to share it using Screencast.com another file is created and it is viewed from that site at this link. When I now click on the history ray of the sun, all the screen captures are shown, the one on my computer and the one located at Screencast.com. My initial screen capture is of an interactive site about passengers aboard the Titanic.
If I wish to embed the screen capture in my blog with HTML code I need to do it via the TechSmith product, Screencast.com, 2GB of space is free. Easy instructions for completing this process are supplied on site.
I decided to visit another interactive website regarding the history of the building of the Titanic and do a video capture. Here is the link to that video.
