kmail on kde 4.2.2

Hi, I just switched to KDE 4 recently. There is a small behavior that is 
different from kmail shipped with KDE 3 and that is quite annoying.

I'm always using an external text editor to write my mails. I do this because 
I often have to review code, and it's much easier to do from vim. I'm also 
used to press Ctrl+Enter to then ship the message so I'm staying far away from 
my mouse.

The problem is, when an external text editor is set, hitting the key 'Ctrl' 
now spaws the editor. In KDE 3, this was not the case. I could hit 'R' to 
first reply, then hit a key to enter the external editor, save & quit and then 
Ctrl+Enter was sending the mail. As a feature/bug request, I'd love to see the 
same behavior in KDE 4. In other words, I don't think that any keyboard 
modifier pushed alone should be able to spawn the external text editor.

Let me know what you think.

Thank you,
