1、Manjaro本身是带着截图软件的，并不需要额外的安装。在桌面右击鼠标，选择应用，助手，就能看到screenshot，点击如图所示。可以选择整屏，当前窗口，还是选择区域。并且可以选择延迟截图。这个真是太方便。
2、在命令行里面输入
xfce4-screenshooter -h
可以看到相关的选项参数
Help Options:
-h, --help Show help options
--help-all Show all help options
--help-gtk Show GTK+ Options
Application Options:
-c, --clipboard Copy the screenshot to the clipboard
-d, --delay Delay in seconds before taking the screenshot
-f, --fullscreen Take a screenshot of the entire screen
-m, --mouse Display the mouse on the screenshot
-o, --open Application to open the screenshot
-r, --region Select a region to be captured by clicking a point of the screen without releasing the mouse button, dragging your mouse to the other corner of the region, and releasing the mouse button.
-s, --save File path or directory where the screenshot will be saved
-i, --imgur Host the screenshot on Imgur, a free online image hosting service
-V, --version Version information
-w, --window Take a screenshot of the active window
3、在设置里面打开键盘快捷键，可以看到默认已经添加了2个快捷键，用户可以自己自行添加和修改。里面的ctrl alt a就是我自己设置的。毕竟qq用习惯了
