From xemacs 24.1.24 here is the ^H-m help and the response to ^H-a "forward".

The key virtue is columnar layout which is visually easier to parse and
faster to navigate.  My final sample shows that gnu emacs does not eschew
long lines.

Subjectively I would say that the one line description at the right edge
of the xemacs output is the least important portion of the display. The
succinctly tabulated properties and columnar arrangement of names makes
spotting naming patterns easier, which in turn helps me either to skip
over entire grouping quickly or to zero-in on those that seem promising.

I also appreciate the ability to narrow the search, though it would be
even nicer if undo were provided.

Hyper-Apropos mode:
Improved apropos mode for displaying Emacs documentation.  Function and
variable names are displayed in the buffer "*Hyper Apropos*".  

Functions are preceded by a single character to indicates their types:
    a = autoloaded, b = byte-compiled, i = internal, l = lambda, m = macro.
Interactive functions are also preceded by an asterisk.
Variables are preceded by an asterisk if they are user variables.

General Commands:

        SPC     - scroll documentation or apropos window forward
          b     - scroll documentation or apropos window backward
          k     - eliminate all hits that don't contain keyword
          n     - new search
          /     - isearch-forward
          q     - quit and restore previous window configuration
  
  Operations for Symbol on Current Line:
  
        RET     - toggle display of symbol's documentation
                  (also on button2 in xemacs)
          w     - show the keybinding if symbol is a command
          i     - invoke function on current line
          s     - set value of variable on current line
          t     - display the C or lisp source (find-tag)


---- gnu emacs ----

Apropos mode:
Major mode for following hyperlinks in output of apropos commands.

key             binding
---             -------

TAB             forward-button
RET             apropos-follow
  (that binding is currently shadowed by another mode)
ESC             Prefix Command
SPC             scroll-up
q               quit-window
DEL             scroll-down
