I can't testify for the original vi (I started using it only in the early
'90 on SunOS 4.0). However I can say that the arrow keys send
two series of character sequences under xterm/gnome-terminal/konsole.
For the up arrow, it can be either ESC-[-A or ESC-O-A (depending on
which the terminal is in, the weather, the following wind). If vi is
configured to take "ESC-[-A" as arrow, then "ESC-O-A" will look
like: <Return to cmd mode>-<Start new line>-A. It's a pain, it has
always been a pain and it will always be a pain until either
someone inserts 2 "up-arrow" control sequences in vi (and others) or
cancel one of the two sequences of arrows in the terminals.
I'll go forward using h,j,k,l...
