Yes - I mean "don't spawn a new window". I wasn't aware of that hotkey.

Other nice features of the message list in Moshi are forward and back
buttons, a browseable history, and a 'reusable' toggle button, to make
it spawn a new message list without learning a hot key. (It is the
forward and back buttons I recognise from Newspeak and Amber.)

Thanks Herbert and Frank for explaining how to uncover the features
for class and message implementor.

I set the preference and still get a new message list for each
implementor I select (trunk 4.5  #12400) when I click the implementors
button - but the list _is_  reused on cmd-m. A win for the keyboard.
Thanks again.

Have fun! David
