Just discovered the ALT+Space shortcut in #Gnome. That allows a screenshot of the current window... (yeah, there is CTRL+Print I know), maximize, move, and so on...
@metal3d You can use GNOME completely from the keyboard. You can even use ctrl + alt + shift to choose between focusing on the topbar or on the windows, the same shortcut in the overview has the options mentioned next to dash, search and apps.
