Linux screenshots, how to take them like a mac

I use Shutter for all my Linux screenshooting needs. You can set it to save screenshots on your desktop, and you can easily set keyboard shortcuts for it, so it should handle your particular question, as well as make most screenshot-related tasks much easier.

On Linux:

1) Applications —> Accessories —> Take Screenshot.

2) Print Screen" (PrtSc) button on your keyboard.

I think there is no Mac equivalent for applekey + shift + 4 or windows snipping tool

Thank you
