You may find it difficult to believe, but the early PCs didn't have a mouse or a touch pad. Everything was done with the keyboard. I know it sounds backward, but even though processors where crude and memory was scarce, using the keyboard you could actually do things a lot faster. By typing a DOS command you can copy a file way faster than by using a graphical File Manager.
I didn't quit using DOS for everyday tasks until the Windows 95 operating system was released. Along with Windows 95, keyboards with a Windows key were introduced. The Windows key is the key with the logo on it just to the left of the [Alt] key. The Windows key adds some functionality that can speed up your access the Windows Desktop and give you quick access to some useful utilities.
Below is a list of Windows key shortcuts that you may find useful.
