[MlMt] Eudora's mail concatenation in MailMate

[Robert Brenstein]

I just discovered that MailMate has a function equivalent to the mail 
concatenation feature of Eudora. I am in 7th heaven, and I thought to 
share this discovery! I saw the setting for this in the preferences 
quite a while ago but only now clicked what it really means. For those 
wondering what I am talking about:

If I double-click a message in MailMate, it opens that message in a new 
window. Nothing special here.

If I double-click a message holding the shift key, MailMate sets a 
filter that shows all messages with the same subject or whatever column 
I was clicking. This is pretty much the same what option-click did in 
Eudora. MM refers to this functionality as searching for related 
messages.

Tip: select the message before you double-click it, so MM does not use 
the first click to select multiple messages.
