Note that by adding "set editing-mode vi" to ~/.inputrc instead of putting "set -o vi" in ~/.bashrc you can extend vi keybindings beyond bash to *any* program that uses GNU readline.

There's a lot more interesting stuff you can do to customise your readline behaviour (including completion options and showing the editing mode in the prompt), see https://www.gnu.org/software/bash/manual/html_node/Readline-Init-File-Syntax.html

In the description of ERR and EXIT, it may be helpful to clarify that ERR gets triggered when a command (either external like "mkdir", "tar", or internal like "pushd") completes with an error status.

EXIT gets triggered when the shell process (script) itself exits.
