Today I have 8 such shortcut keys which are going to be very useful in your daily life. And some such shortcut key that will helpful for finish your work quickly.

1. window +D : some people are using window+m which minimizes all applications. Windows+D and Win+M are very similar, but I prefer Windows+D because it’s a toggle and because not every application can be minimized.  And If You want to Maximize window those you minimize so just click again win+d it will maximize window. Windows+D is just a little bit more generally useful.
    
2. Alt+F4:  Alt +F4 is used for close a window. If you are playing game , using any window application and you want close it just on click  than Alt +F4 is close window . either You can use it on home screen as shut your pc and restart.
    
3. Ctrl+window+D:  This shortcut key is really awesome and this is my favorite key because when I need two desktop it is helpful .Just  click ctrl+window+D And boom your entered on second desktop. You can easily move from one window to another just click window button + tab .
4. Ctrl + number key:  when you are writing blog and researching  on web we opened many  tabs in chrome then ctrl + (1,2,3,4…..N) is use as move one tab to another in corresponding way in your tab bar. 

And instead you can also use the  ctrl+tab to move it from one tab to another.

  5. Ctrl + Shift + t: If you close any tab by mistake, then you don't need to go to history and find them just click ctrl+shift+t button it will bring your tab return as you use it before.

  6.ctrl+W: This key is very helpful when you hurry to close tab in chrome, and it also use as close any application  like file explorer, MS office etc.
