Just follow these steps and you can create shortcut keys for your favorite program.
-> First open that folder which contains that program or go to that program. Here I am taking Adobe reader for example.
-> Now right click on the icon of that program.
-> Select properties from option
-> Now you can see there is an option to set shortcut key
-> Now just press that keys and your program will open.
In this type of shortcut keys, we have to press Ctrl+Alt followed by the shortcut key.It is some what long but still we can make our work faster by creating shortcut keys for those programs that we use frequently.
