I am not sure if this will work either, I cant verify it right now but-
You can enable vi mode of editting the command line by first typing -
set -o vi
After that you can type "esc" when you want to move in and out of the vi mode.
So to access your history - type "esc" and then type "k" to go above and "j" to go below in your history.
Type "esc" to come back to command mode.
All other commands used in VI will work in the vi mode.
