Yeah IMO not so much shortcuts but file management is often lost on the old and the young.
What is a file. What is a file type. What is file size. Where do files go when you download them. What is your user directory. How do you rename files. What is a file sync app like google drive.
This stuff could save so many people so much time. Every day millions of professionals are emailing clients “Thanks for sending that though, but it looks like you’ve emailed me a shortcut instead of the actual file.”
