Keyboard shortcuts for screenshot on Ubuntu 20.04 running on a MacBook Pro
For frequent sharpshooters, like me, a short-cut on Mac Key boards is difficult. There is a method of launching the "screenshot" app, for which we need to go to applications every time. As is the case with windows keyboards, PrntSrcn and other combination are quite handy to clip a part of a given window, a window itself or the whole screen. Do we have such thing for mac keyboards as well?
Applications → Settings → Keyboard shortcuts - Doesn't allow to reset the other shortcuts, where it appears everywhere the combination of Print key.
Solution 1:
macbook pro does not have a print screen button due to touch bar, which is the default button in case of PC.
The default button for screenshot can be checked in settings. Press super key (windows button on PC or command button on mac), and type shortcut and select keyboard shortcuts.
Start typing screenshot and shortcuts related to screenshots will appear in front of you.
If you want to enable custom shortcuts, then erase the screenshot typed earlier and scroll down to bottom and click the plus sign at the very bottom. For the name field enter screenshot full (or whatever you wish to name it) and in the command section type gnome-screenshot and click on the set shortcut and press the key combination you want to take screenshot of the whole screen.
If you want to take screenshot of an area which you want to select (a crosshair will appear and then you have to press and drag to select an area and screenshot will be taken of this area only), then instead of just gnome-screenshot type gnome-screenshot -a and then select the key combination you want.
If you use gnome-screenshot -w in the command field then it will take the screenshot of the current windows which is highlighted.
All these screenshot will be saved to the Pictures folder in the home directory.
Just as we used -a and -w at the end of gnome-screenshot command, there are several others called as flags. Open terminal and type gnome-screenshot -h and this will display all the available flags.
