[MlMt] Move focus to message list

[Stefan Buehler]

Dear MailMate experts,

I like using the keyboard and avoiding the mouse. This works very well 
in MailMate, but I often have the problem that when I do a search or 
jump to a mailbox, the focus is then in the search field or the mailbox 
list, and not in the message list where I need it to be to deal with the 
messages.

I can move focus along with the tab key, but it is a bit unpredictable 
how many times I have to press it to come to the message list.

So, it would be great to have a keyboard shortcut to move focus to the 
message list directly.

I thought I could achieve this with the last two keys (f and l) in the 
keyboard shortcuts file like this:

	"l" = {
		// 0 In+Sent
		"0" = ( "goToMailbox:", "B6C88ECF-C0A4-4B8F-AD99-D29E352D60FD" );

		// 1 Wichtig
		"1" = ( "goToMailbox:", "9C4141C4-5D02-46C2-8B86-82825D65C9BB" );

		// 2 Normal
		"2" = ( "goToMailbox:", "81B7C934-ABAD-4349-8129-588BD1E94ED6" );

		// 3 Unwichtig
		"3" = ( "goToMailbox:", "4272D314-52C4-4FF9-9FA9-1DE1BD287BC3" );

		// 4 Other unread (bereits in Folder abelegte Mails)
		"4" = ( "goToMailbox:", "6FC03EEB-FBC4-4A91-B450-5A0C1330CBDB" );

		// Show all from same thread
		"t" = ( "showThread:" );

		// Show all from same correspondants
		"c" = ( "showCorrespondence:" );

		// Select first message row
//		"f" = { "selectFirstMessageRow:" };

		// Select last message row
//		"l" = { "selectLastMessageRow:" };

	};

With the lines commented out like this, keyboard shortcuts work. But if 
I uncomment one or both of the last two entries, all custom keyboard 
shortcuts stop to work.

Any ideas?

Cheers

Stefan
