How to move multiple messages in mutt

Question

Before all of my messages were in one maildir. Now I want move all arch-general mail to another one.

From here, I see:

"move" as we know it from other places is "save" in mutt. 
"save" as we know it from other places is "copy" in mutt.

~e EXPR         message which contains EXPR in the ``Sender'' field

so I use pattern in index

'T'  and  '~e arch-general' then  's'

but just one message moved.

How can I move all pattterned messages to another dir?

As with several key-bindings in mutt, this one seems to be mode-specific. (A list of mutt modes is available here.) It works in index mode, but if you attempt to use it in pager mode, mutt will respond with the error message, Key is not bound. Press '?' for help. This is true even if the index is showing, e.g. if you have a line like set pager_index_lines=8 in your .muttrc. – Bedtime
