M-RET to open buffer in new frame in helm-mini?

Question

Is it possible to add a key binding M-RET to helm-mini which would open the selected buffer in a new frame instead of in the current window?

Answer 1

This should already be available as helm-buffer-switch-other-frame, bound to C-c C-o. You can see available actions by hitting TAB while in a Helm buffer.

To bind M-RET to helm-buffer-switch-other-frame, add the binding to helm-buffer-map:

(define-key helm-buffer-map (kbd "M-RET") #'helm-buffer-switch-other-frame)
