need couple of ksh tricks please

1) I ran myScript with 2 arguments, I meant to use 3
if I do r my, it will rerun it with the 2 arguments. is there a way I can do r my and add a third argument at the end?

2) say I did

myAcript.ksh 2 5 7 8

I realise my typo. is there an easy way to redo the command replacing A with S?

You can use vi commands to edit the line, Google on "vi commands".

vi commands work only if vi mode is on. I use emacs mode. You them them on with one of:
set -o vi
set -o emacs
But by default neither is on.
