namesel is a newer command added after version 1.2304 - get the
recent snapshot to use this command:
The release notes for this snapshot list what has changed since 1.2304:
The links I included in previous messages were to "development"
documentation, which will always be newer than what you have
(although mostly the same if you have a recent version). The
documentation included with a download is more synchronized - you can
access and search your local copy of the documentation using the
Chimera Help menu.
