AS4 and AS5 key maps

On the AS4 box, you may use the right arrow key to move the cursor around, but on AS5, you may find it echo back something like this.

   ‘alt+left/right’ result in adding character  ‘[D’ and ‘[C’

  echo ab  d cd   [D[D[C[C

But you can try the following.

ALT + b : Backward

ALT + f: Forward

To follow up

Is there any way to map‘alt+b/f’ to ‘alt+left/right’ ?

set-o vi # I assume alt + left/right will work

set -o emacs # this is how alt + b/f works

And it continues.

but tried, this is necessary to work in emacs

Just tried, alt +left/right won't work in both modes without this (on AS5):

bind '"\e[1;3D":backward-word'
bind '"\e[1;3C":forward-word'
