[MlMt] Keybindings for "Thread" and "Correspondence"

[Jack Brannen]

I configured my keybindings to include commands to show the thread and 
correspondence views, as included here:

But I find these don't work the same way as the thread and 
correspondence BUTTONS in that they filter the current folder only. The 
buttons filter all messages automatically.

Can I make the keybindings work like the buttons and filter all 
messages?

Thanks!
