### 2.18 Misc Group Stuff

`v`
  The key `v` is reserved for users. You can bind it to some command or better use it as a prefix key. For example:

                (define-key gnus-group-mode-map (kbd "v j d")
                  (lambda ()
                    (interactive)
                    (gnus-group-jump-to-group "nndraft:drafts")))

  On keys reserved for users in Emacs and on keybindings in general See Keymaps.

`^`
  Enter the server buffer (`gnus-group-enter-server-mode`). See Server Buffer.
`a`
  Start composing a message (a news by default) (`gnus-group-post-news`). If given a prefix, post to the group under the point. If the prefix is 1, prompt for a group to post to. Contrary to what the name of this function suggests, the prepared article might be a mail instead of a news, if a mail group is specified with the prefix argument. See Composing Messages.
`m`
  Mail a message somewhere (`gnus-group-mail`). If given a prefix, use the posting style of the group under the point. If the prefix is 1, prompt for a group name to find the posting style. See Composing Messages.
`i`
  Start composing a news (`gnus-group-news`). If given a prefix, post to the group under the point. If the prefix is 1, prompt for group to post to. See Composing Messages.

  This function actually prepares a news even when using mail groups. This is useful for “posting” messages to mail groups without actually sending them over the network: they're just saved directly to the group in question. The corresponding back end must have a request-post method for this to work though.

`G z`
  Compact the group under point (`gnus-group-compact-group`). Currently implemented only in nnml (see Mail Spool). This removes gaps between article numbers, hence getting a correct total article count.

Variables for the group buffer:

`gnus-group-mode-hook`
  is called after the group buffer has been created.
`gnus-group-prepare-hook`
  is called after the group buffer is generated. It may be used to modify the buffer in some strange, unnatural way.
`gnus-group-prepared-hook`
  is called as the very last thing after the group buffer has been generated. It may be used to move point around, for instance.
`gnus-permanently-visible-groups`
  Groups matching this regexp will always be listed in the group buffer, whether they are empty or not.
