Title:  Hypertexting to help from list-commands buffer

The command  list-commands  (C-h c), creates a buffer of commands which may be
double-clicked  on to open  the  relevant  help  file.  This is a good  thing.
However, this cannot be done via the keyboard! The following macro will do it.
Paste the  following  into file  "mylists.emf"  and then it will find the help
using the "return" key. This type of mechanism should go into the base macro.

;  Description   : Extensions to access the help for the command from the

; Local macro to process the links from the keyboard.
; Bound to <RETURN>. Note that we process from the
