[orca-list] Disable the preview pane in thunderbird

[Justin Harford <blindstein gmail com>]

Hi all

I feel like this has come to the list before, but I don't think I have 
my terminology right to find it on google. I want to disable the feature 
on thunderbird where it shows the message automatically when it is 
selected. I would rather just press enter on the messages to open and 
read them.

If anyone could refer me to a quick solution or article about it, that 
would be great.

Regards
Justin Harford
