Crafted emacs doc symbol void kdb

On initial use of a new crafted-emacs I’m using the evil example but running into a error in my init.el Symbol's function definition is void: kdb on this line (customize-set-variable 'evil-escape-key-sequence (kdb "jj")) any idea on what I need to address this?

That’s a typo, kdb should be kbd (for keyboard). The example online also uses kbd.

Ah! Thank you @ashraz I also just changed it to (customize-set-variable 'evil-escape-key-sequence "jj") string instead of the symbol and that works. What would be the benefit of using kbd?

See M-: (kbd "jj") RET.
