I like to use pre-set Shortcut keys in Windows 10 by setting them in desktop short cuts I create from files or URL's etc. I can open web pages I use in my work and files I keep my records on, etc. with quick key strokes. No problem opening a file that runs in a Windows program, but I can't seem to make a shortcut boot a Mac Numbers file using a CTRL-Alt-(key) as with others. By right clicking on the shortcut I can choose "Open on Mac" and it boots it up right away, perfectly. Is there any way to make it work using a regular shortcut key? Some trick?
