But now `C-h m' displays:

m               proced-mark
d               proced-mark-alt

that causes a false impression that these commands are different.

A simpler fix would be just changing the order of `d' and `m' bindings
in `proced-mode-map' like:

@@ -459,8 +459,8 @@
     (define-key km [down] 'next-line)
     (define-key km [up] 'previous-line)
     ;; marking
-    (define-key km "d" 'proced-mark) ; Dired compatibility ("delete")
     (define-key km "m" 'proced-mark)
+    (define-key km "d" 'proced-mark) ; Dired compatibility ("delete")
     (define-key km "u" 'proced-unmark)
     (define-key km "\177" 'proced-unmark-backward)
     (define-key km "M" 'proced-mark-all)

But really I don't understand why `m' should be preferred to `d'?
In Proced like in Dired, `d' flags a process for deletion, and `x'
commits the operation.  `m' is an alias for `d' because currently there
is no more dired-like operations on processes.

The only reason to prefer `m' over `d' in the documentation now is
the fact that proced-mark marks a process with the "*" character
(like dired's `m' does) instead of "D" (like dired's "d" does)
until someone comes with an idea of different operations
for `m' and `d' in Proced like in Buffer-menu where they are bound
to different commands:

  m -- mark current line's buffer to be displayed.
  d -- mark that buffer to be deleted, and move down.
  x -- delete or save marked buffers.
