An idea: what if running a program with -h or --help described the flags and arguments passed in, rather than everything? Subcommands get this treatment (e.g. git log -h), why not everything else?
Say you want to know what fzf +s does. Running fzf -h prints 89 lines of text. The +s flag is on line 17. That's 72 lines of scrolling. If the help was contextual, you could run fzf +s -h to see just the help for +s.
We could go further and print argument values too. A hypothetical example:
$ fzf +s -q $(date) --preview="ls {}" -h
usage: fzf [options]
+s, --no-sort Do not sort the result
--prevjew=COMMAND Command to preview highlighted line ({})
value: "ls {}"
-q, --query=STR Start the finder with the given query
value: "Fri 15 Apr 2022 19:15:38 BST"
You could copy any command invocation from the internet and add -h to understand what it does.
