Switching groups and including messages

[Krishnakumar B]

Hi,

Does someone know if gnus-summary provides a way to navigate between
different summary listings without closing the current group summary?
Something like gnus-visit-group, which will automatically open up that
group, unlike switching buffers, which requires an extra RET to open up the
article buffer corresponding to the summary listing.

Also, in message mode, is it possible to include another message in the
same group/different group by number when forwarding or as an attachment?

Lastly, is it possible to toggle between showing new messages/old+new
messages in the summary buffer?  Frequently, I have a need to search
through the group's messages to switch to a different message.  Currently,
I close the current open summary buffer, re-open the same group, and then
search which seems to be brain-dead.

I am using Gnus v5.10.6 on Debian/GNU Linux (sarge).

-kitty.
