Freron MailMate

I was trying to set up a custom keybinding to select all messages in a thread in the current mailbox, and open a single window showing them all. I thought I could do this by assigning ( "selectThread:", "openMessages:" ); to a key combination in a custom keybinding file. My first attempts at this failed: all messages in the thread were selected, but MailMate then opened one window for each message. When I revisited this today, a bit of trial-and-error showed me why it wasn't working.

I was trying to use a key combination with shift. For some reason, any key combination that includes shift will always open several individual message windows instead of a combined one. I think this is a bug (or at least it's unexpected).

So this works, producing the expected behaviour of opening a single window showing multiple messages:

 e  = ( "selectThread:", "openMessages:" );

And this doesn’t work, it opens several windows, one per message:

 E  = ( "selectThread:", "openMessages:" );
