This idea came up several times here, and was met with a general
agreement, but no one stepped forward to work on those "most common
configurations".  And it is not easy to do, since the configurations
depend on the needs of the user (whether the user is a programmer and
in what language(s), what other tasks and jobs does the user want to
accomplish in Emacs -- email, todo items, etc.) and also some general
user preferences (mouse vs keyboard etc.).

Patches welcome, of course.

The Emacs apropos commands, if used wisely, should help you.  You
might find that some of our documentation needs to be enhanced to make
discoverability easier, in which case please report the deficiencies,
so we could make this better.

Some Emacs commands I suggest for this are:

  C-u M-x apropos
  M-x apropos-documentation
  C-h R elisp RET followed by 'i' (Info-index) and the subject
