From Richard Rauch:

> As for ed(1)...no, it's not what most people would call user-friendly.
  It is a traditional old editor that you can find on every system.  It
  doesn't present menus or use graphics of any kind.  But it is reasonably
  powerful, and not too difficult to learn for basic tasks.

> FreeBSD does have a user-friendly editor that ships with their base
  system, I think.  There was talk about doing one for NetBSD.  Some of us
  suggested that a short help-page for ed was a better idea, since ed is
  easy to learn (if cryptic at first).  Neither approach was taken, so you
  are left with /bin/ed and only ed's man-pages for help.  If you don't know
  that ed is there, or don't know how to use it (and don't know about/can't
  use the man pages) you are kind of stuck.

> In your case you have other installed OS's.  ed is common so that you
  should be able to use the man pages from another OS to get around NetBSD's
  ed.  Also, I have a short (dense)  screenful of ed-help that I wrote; if
  you like, I can send it.

Maybe I confused ed with ae?  Both have two letters, and they're not vi, or is
ed a branch of vi?  I have a little experience with elvis under Linux, some more
experience with the 32-bit DOS version of vim 6.  But this vim 6, or at least
the DOS port, has a serious bug with regard to editing multiple files
concurrently and switching back and forth between them, as I so frequently do
with text editors, enough to make this function unusable in vim 6, at least the
DOS port.  I want to download and run the NetBSD and Linux versions, making sure
the version is not less than 6, for comparability.  vim 6 has good
documentation.

Traditional Unix text editor is vi, is this correct?  I thought NetBSD was
supposed to use nvi as default editor.  Other OSes I have, besides NetBSD, are
Linux and DR-DOS 7.03.
