(I realized that you don't need to unprotect a function to change
its usage message: hence the following revision of my previous
message)

Jack:
You can make you own additions as in the following example for Plot.
You might put the extensions in a package (MoreHelp` ?) and put
this into your init file for automatic loading at the start of each
session.
Make your additions (you don't need to unprotect Plot)
Plot::usage = StringJoin[Plot::usage;, "\nMy additions"];
Here they are
?Plot
Plot[f, {x, xmin, xmax}] generates a plot of f as a function of x
from xmin to xmax. Plot[{f1, f2, ...}, {x, xmin, xmax}] plots
several
functions fi.
My additions
