gnus: Marking Groups
2.8 Marking Groups
==================
If you want to perform some command on several groups, and they appear
subsequently in the group buffer, you would normally just give a
numerical prefix to the command. Most group commands will then do your
bidding on those groups.
However, if the groups are not in sequential order, you can still
perform a command on several groups. You simply mark the groups first
with the process mark and then execute the command.
‘#’
‘M m’
Set the mark on the current group (‘gnus-group-mark-group’).
‘M-#’
‘M u’
Remove the mark from the current group (‘gnus-group-unmark-group’).
‘M U’
Remove the mark from all groups (‘gnus-group-unmark-all-groups’).
‘M w’
Mark all groups between point and mark (‘gnus-group-mark-region’).
‘M b’
Mark all groups in the buffer (‘gnus-group-mark-buffer’).
‘M r’
Mark all groups that match some regular expression
(‘gnus-group-mark-regexp’).
Also Process/Prefix.
If you want to execute some command on all groups that have been
marked with the process mark, you can use the ‘M-&’
(‘gnus-group-universal-argument’) command. It will prompt you for the
command to be executed.
