Actually, I bind this functionality to the `J' key.  And what turns
out to be quite handy is to have this available in the Summary buffer
as well.  (To make binding easier, the implementation I gave should be
changed so that there is a function gnus-group-select-a-group, instead
of mixing it into gnus-group-jump-to-group.  See below.)

Since Gnus is designed for reading groups, I thought that a keystroke
devoted to selecting a group whose name is supplied by the user would
be useful.  But if you don't like it, I'll just put it in my .gnus.

(defun gnus-group-select-a-group (group &optional all)
  "Select newsgroup GROUP.
Interactively, query for group name with completion.
No article is selected automatically.
If ALL is non-nil, already read articles become readable.

  (interactive

	  (gnus-read-active-file-p)
	  nil
	  'gnus-group-history)

  (when (equal group "")
    (error "Empty group name"))

  (gnus-group-read-group all t group))
