Gnome-Shell It is fashionable, and even if it were not, its use in most distributions will be in a very short term.
Like any good desk, Gnome-Shell It also has its keyboard shortcuts and even some very surprising ones that will allow us to move between the Desktop and Overview (General Information, so to speak. It's the view you get when you click Activities). So let's take the opportunity to know some.
- Windows key: Switch between applications or desktops. Organize the open windows so that you can see them all in Overview and select the one you want.
- Alt + F1: Switch between Overview and Desktop.
- Alt + F2: The running of a lifetime.
- Alt + Tab: Switch between applications using the pop-up window.
- Alt + Shift + Tab: The same as the previous one, but with the applications in reverse.
- Alt + [Down Key + Tab]: When we execute this combination, the same is shown but we can see which windows each application has open.
- Ctrl + Alt + Tab: Open accessibility switch.
- Ctrl + Shift + Alt + R: Just great. With this combination of keys we can make a Screencast of our Desktop. We start and end it with the same combination.
- Ctrl + Alt + Up / Down Arrows: Switch between desktops (similar to Compiz).
- Ctrl + Alt + Shift + Up / Down Arrow: We move the current window to a different desktop.
Especially the option to do the Screencast It's amazing .. You can see these shortcuts and their explanation in this link.
