And solved this problem also:
(setq gnus-group-jump-list
(list
'("d" "nndraft:drafts")
))
(defmacro gnus-group-jump-bind (key-binding group-to-jump-to)
`(define-key gnus-group-mode-map ,(symbol-value key-binding)
(lambda ()
(interactive)
(gnus-group-jump-to-group ,(symbol-value group-to-jump-to)))))
(defun gnus-group-do-jump-bind ()
(dolist (this-jump gnus-group-jump-list)
(let ((this-group (second this-jump))
(this-key (concat "vj" (first this-jump))))
(gnus-group-jump-bind this-key this-group))))
(gnus-group-do-jump-bind)
And this does what I want. A problem could be that:
(gnus-group-jump-bind "vjd" "nndraft:drafts")
does not work anymore, but just always use variables solves that
'problem'.
