'help' is already the shell's built-in help function in most cases. That'd be a poor choice of alias.

There are a small number of seed keywords which are ueeful to know. 'help' (shell), 'apropos', 'man' (online manual), 'info' (GNU documentation), and dwww (local documentation presented through a Web interface, available on Debian-based Linux, see https://ostechnix.com/dwww-view-complete-debian-documentatio...) are among them.

Knowledge requires a certain baseline.

If that's too much ... perhaps a GUI is in fact advisable.
