are doing.
Description of Problem:


Steps to reproduce the problem:
1. Open Evolution mail
2. In order to see source of any email you have to switch
view - message display - show email source
3. In order to get back to normal view you have to go to menu again
and change there

Actual Results:
You have to go tomenu twice to see the source of
the message

Expected Results:
In addition to existing view mode (source) I would expect shortcut
key to see the message source in new window since I view the
messages in normal mode and very rarely viewing the source.
The shortcut key for [view source in new window] will save my time.

How often does this happen? 
n/a

Additional Information:
Mozilla's mail C-u shortcut is fine.
