Points

You don't need any script file to check bindkey behaviour.

Just hit keys and binding.

You can reset all bindkeys by bindkey -d or restart shell ( e.g exec $SHELL or close window and reopen windows )

Bind string

bindkey -s A "some string"

Hit capital letter "A" key and some string appears.

Bind zle widget

bindkey B accept-line

Push B key and Enter happens and.

"accept-line" is zle basic widget.

Show all bindkey mappings

bindkey

Enter with no arguments.

You will see all bindkey mappings and zle widgets list.

"^@" set-mark-command
"^A" beginning-of-line
"^B" backward-char
"^D" delete-char-or-list
"^E" incremental-select-command-history
...

Bind custom widget by shell function

Defune shell function.

function _hello_zle(){ echo "Hello zle original widget" && zle reset-prompt }

by zle command.
