Thank you for this guide! I guess I wasn’t clear about the functionality I was looking for. I want to be able to draw a shape, say a circle instead of a rectangle, and have the screenshot only be of what I’ve circled. Snipping tool in Windows had this functionality, you could select that instead of a rectangle or square it would be freeform. I wanted to know if there was any Linux equivalent, because I haven’t been able to find one on my own.

And that explains it; never knew they were called that.

I’ve never understood this one.
