[MlMt] Key Bindings: Select Thread?

[Niels Kobschätzki]

Hi,

in the Gmail-Key Bindings-list stands the following:
        "*" = {
                "a"    = "selectAll:";
                // Make a feature request if you need any/all of the following
                // * then n     Select none     Deselects all mail.
                // * then r     Select read     Selects all mail you've read.
                // * then u     Select unread   Selects all unread mail.
                // * then s     Select starred  Selects all starred mail.
                // * then t     Select unstarred        Selects all unstarred 
mail.
        };

Is there a way to select all mails in a thread for being able to select 
easily a thread in the inbox and move it to another one?

And I'd like to select all read mails and deselect all mails.
