My arrow keys don't work in vi in insert mode at home, they just each insert a newline and a capital letter, like 'A'. Is there a way to fix that?
I presume you're using vim as this is tagged as Linux. Try:
:set nocompatible
(You may want to configure your .vimrc with this by adding this command to it. Create a new .vimrc file if not already present in your home directory, run echo $HOME
to check home directory path.)
