Open custom file with keyboard shortcut On my Mac, I have some applications that were recently made in Java that I will be using quite alot. I want to know, is there a way that I can bind a shortcut on the keyboard to open the file? 

For eg. CTRL + CMD + OPTION = Open test.jar located on Desktop.

Is there any 'vanilla'  way or if there is, any 3rd party software that can allow me to do so?
