What if you need to highlight/call attention to any fragment of your worksheet, be it a piece of data table or a picture/chart, for a presentation or just for printing a report?
You can do it quite easily in Excel. Let's consider a picture. You may need to overlay an enlarged small fragment of your picture onto the original whole picture. To do that you can use the Windows "Snip & Sketch" utility (the shortcut to invoke it, is: Windows Logo key + SHIFT + S). You can select either rectangular or free-form snip. After getting the snip, format/enlarge it as needed, in a way attracting attention to it, and move it to a desired position. This is an example of the 'picture in picture':
The same can be done also with any chart/graphics.
