I was playing around with Windows 8.1 on my computer and I figured out there are some cool shortcuts maybe you haven’t known.

Did you know that the icons in your task bar starting after the start button on the left bottom corner of your screen are numbered from 1 - 9.

+ 1 - opens the application or whatever your 1st icon after the start menu
+ 2 & and so on. Does the same.
+ ShiftKey + [n] -  opens up another instance of whatever that icon points to.
Now if that is not clear, I hope the following image kind of helps understand that.

More coming around soon.
