viins is the default (after I run bindkey -v) and vicmd can be
abbreviated with -a.
bindkey -v
# Also use jj to exit insert mode.
-bindkey -M viins 'jj' vi-cmd-mode
+bindkey 'jj' vi-cmd-mode
# I don't need the arrow keys, I use ^N and ^P for this (see below).
-bindkey -M viins -r '^[OA' '^[OB' '^[OC' '^[OD' '^[[A' '^[[B' '^[[C' '^[[D'
+bindkey -r '^[OA' '^[OB' '^[OC' '^[OD' '^[[A' '^[[B' '^[[C' '^[[D'
# Also not in Vi mode.
-bindkey -M vicmd -r '^[OA' '^[OB' '^[OC' '^[OD' '^[[A' '^[[B' '^[[C' '^[[D'
+bindkey -a -r '^[OA' '^[OB' '^[OC' '^[OD' '^[[A' '^[[B' '^[[C' '^[[D'
