Whenever we work with any tool, the first and the foremost thing we search for is the shortcut list. I too needed it most as I had to open the labels over and over again just to find the shortcuts.
I googled it out but was unable to find a full list. So thought to make one for myself and as I have already made it then why not share it as well.
So here goes the list. Though a short one, but contains all the important ones.
