How do I load files using full path?

This seems to require files being in the same directory:

;(define-nyxt-user-system-and-load nyxt-user/basic-config
;  :components ("keybinds"))

Any way I can use aboslute paths herei

@daltor define-nyxt-user-system-and-load works as long as ASDF can find the system. If this is gibberish to you, then ignore it since I don't know how comfortable you are with Common Lisp.

You may try to add (nyxt::load-lisp "/path/to/file") to your config.
