The Show Floating Thumbnail option helps you work more easily with a completed shot or recording - it floats in the bottom-right corner of the screen for a few seconds so you have time to drag it into a document, mark it up, or share it before it’s saved to the location you specified. For example, you can choose to set a timed delay or show the mouse pointer or clicks, and specify where to save the file.
The available options vary based on whether you’re taking a screenshot or a screen recording.
