I'm used to a Mac and its screenshot keyboard shortcuts. When I go home and use my PC, I get frustrated by the process I have to adopt: open Snipping Tool, snag a bit of the screen, open it in Photo Viewer, Save it, go to the location of the file, and open it in Photoshop or import into Illustrator.
With Lightshot, I can just snip a bit and copy it, then paste it into my document. HUGE time saver. I'm installing this on my Mac at work tomorrow. Thank you Serg!!
