Using i3 as a Linux window manager

The i3 is used to maximise the actual screen and use only the keyboard

The i3 wm enables users to perform tasks without a mouse, utilising keyboard shortcuts. Application windows are maximised and can also be moved and resized using keyboard shortcuts. Following a brief period of familiarisation, users can work at a faster pace as their hands remain in constant contact with the keyboard. Additionally, switching between the active window and the virtual screen is a rapid and straightforward process. The concept ensures that the screen is consistently in use, and that windows cannot overlap.
