To get the most out of it and avoid wasting time with the mouse, you can use various keyboard shortcuts for taking screenshots . For example, use Ctrl + C to copy the image to the clipboard or Ctrl + S to save it directly to your hard drive. If you make a mistake, the classic Ctrl + Z undoes the last action , while the ESC key closes the screenshot tool instantly.

One very useful detail is that you can move the selection pixel by pixel using the arrow keys or resize it by holding down the Shift key. For Linux users, it is highly recommended to configure a custom shortcut in the system (as a key combination) associated with the command flameshot gui to summon the capture device in the blink of an eye.
