Using the mouse, keyboard and menus can take up a lot of time, which can be saved by using keyboard shortcuts. This not only saves time, but also makes users more efficient.
Did you realize that it takes up to two seconds to switch from the keyboard to the mouse each time you type? If a person works eight hours a day, switches from keyboard to mouse once a minute, and there are about 240 working days in a year, the time wasted (according to Brainscape’s calculations) is: [waste 2 seconds per minute] x [480 minutes a day] x 240 working days every year = waste 64 hours a year This equates to lost eight working days, so will learn keyboard shortcuts to improve productivity by 3.3% (www.brainscape.com/blog/2011/0… ) .
Keyboard shortcuts provide a faster way to perform tasks that would otherwise require multiple steps using a mouse and/or a menu.

I omitted well-known shortcuts, such as copy, paste, etc., as well as shortcuts that are not used often. Readers can refer to online resources for a complete list of shortcuts. Note that the Windows key has been renamed the Super key in Linux.
