Jay,

  That is because arrow keys do not work in vi to move.  You may think
they do "because it works in vim, or vile, or elvis" but those are
improvements which the original versions did not do.  If you want to
review your history you need to hit ESC then 'j' or 'k'.


  Many people notice that if you hit down then up scrolling through
the history "works"... I don't know why this is, it seems like a bug.
on standard terminals:
  up key is =3D=3D ESC [ A
  down key is =3D=3D ESC [ B
I don't understand how those combinations of characters move around=20
in vi-command mode.


  Since most every GNU utility that provides a command mode uses=20
libreadline I suggest that if you really do like the vi mode, that
you add:
  set editing-mode vi
to your own ~/.inputrc which libreadline uses to configure itself, this=20
will make things like bash, gdb, and the rest behave the same way on=20
startup.
