Trying to make keybinding in spacemacs

Question

I'm trying to bind ",," to eval the topmost S-expression containing the cursor in common lisp layer, from this page I assumed it would be done like so:

(spacemacs/set-leader-keys-for-major-mode 'common-lisp-mode "," 'slime-eval-defun)

Which returns nil, but when I try to use it, says it's undefined.

Thinking that "," may be special in some way I tried this:

(spacemacs/set-leader-keys-for-major-mode 'common-lisp-mode "eh" 'slime-eval-defun)

with the same outcome.

What am I doing wrong?

Answer 1

Ok, I had to assign it for lisp-mode , not common-lisp-mode , then

(spacemacs/set-leader-keys-for-major-mode 'lisp-mode "," 'slime-eval-defun)

just works.
