Switching to a different group from the summary buffer

[Krishnakumar B]

Hi,

Maybe I am missing an obvious keystroke, is it possible to switch between
groups without going to the Group buffer? I know about the n, p, k, and
<Space> keys which offer to go to the next unread group, when I done
reading the last article in a group. But frequently I need to switch
between groups, without reading all the articles in the current group, or
closing the current group. But I didn't find any keystroke which will open
up an existing group from the summary buffer of another group.
