List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 08 Feb 2012 08:02:42 -0000 With an argument, record and reply the state of the buffer during `notmuch-show-refresh-view'. In this context, "state" is defined as: - the open/closed state of each message, - the current message. Traditional use of refresh with the = key does not retain the state. The recently introduced toggle commands ($, !, < and >) do retain the state. --- emacs/notmuch-show.el | 56 ++++++++++++++++++++++++++++++++++++++++++------- 1 files changed, 48 insertions(+), 8 deletions(-) diff --git a/emacs/notmuch-show.el b/emacs/notmuch-show.el index 6c79511..a668625 100644 --- a/emacs/notmuch-show.el +++ b/emacs/notmuch-show.el @@ -951,7 +951,7 @@ current buffer, if possible."
