Here I listed some of the Keyboard key and it's explanation. Just go thorough it.

1.Windows= The Windows key has the Microsoft flag logo. It is find between the CTRL and ALT keys. This is commonly used with another key to perform normal option like following.
Windows+E= To open explorer window
Windows+D= To minimize all open window

2.Tab = The tab key is used to give some space at the starting of the line of the document. So that it can be identified as paragraph.
If you used it with "alt" keyword, then it used to switch between all open windows.

3. Caps lock= It is used to toggle between upper case and lower case.
