Locate the icon of the program that you want to launch faster. Then right click on it and select Properties.

Then put the mouse cursor in the Shortcut Key box (click on the word None )

Choose a key combination that you want to use as a shortcut key using any combination of CONTROL, ALT and/or SHIFT keys along with any regular keyboard character (alphanumeric). Then, on your keyboard, hit that key combination. You will see your key combinations appear as you press them

Then Click Apply and you are done. You can test it out immediately by just hitting the same key combination. If your program opens, then it is working.
