OT: Preferred Applications?

[Dave Hunt]

Hi,

I have somehow managed to break the default email client setting in 
Ubuntu 11.10.  In Gnome Control Center, I find, under 'system info', the 
setting for default web browser, image viewer, music player, and video 
viewer.  Documentation suggests that email client should be another of 
these configurable settings.

I think the trouble started when I updated Evolution from Proposed 
(don't do this), and rolled Thunderbird back to 3.1, for better 
accessibility with Orca.  My keyboard shortcut 'ctrl+alt+m' now does 
nothing.  Is there a cli command or can I edit a text file to fix this?


Thanks,
