If you wanna show more details and stuff that disappears when you just make a screenshot by pressing the Print key, you have a Screenshot app as well.
See, it’s simple, as can be:
It lets you …
- grab the whole screen
- just the active window
- or make a rectangle around the area you wanna shoot
- and you have a timer option (here in this example I chose 20 secs) to get menus up on screen if you wanna capture them in the shot
The screenshot program is in the Accessories menu. At least in Mate. No idea where it is in Cinnamon but at least the app looks the same.
And now … have fun with Linux! It’s awesome!
