I am a long time fan and user of Pegasus Mail (probably 20 years or so), so I was shocked to learn something new today, and what I'm wondering is: can this feature be disabled?

By complete accident (I was intending to press Ctrl-S to save an e-mail to HTML) I pressed Ctrl-D while reading a message and it immediately disappeared. It did not get moved to another folder and it did not appear in "Deleted Messages"!

As you know, if you press D or Del in a message, or in folder view with one or more messages selected, those messages are moved to the "Deleted Messages" folder. This is fine. That's not what I'm referring to.

After a little further experimentation, I confirmed that Ctrl-D does this "instant and hard" delete in the message viewer but not in folder view. In folder view, if you press Ctrl-Del, you get this same "instant and hard" delete, but not in message viewer.

I do not find this information in the Help file, but perhaps I missed it. I do have occasion to use keyboard shortcuts like Ctrl-C and Ctrl-S on a regular basis, so an accidental Ctrl-D is not an entirely surprising mistake on the rare occasion.

And, now that I think of it, there have been one or two times over the years when a message disappeared and I never did find it!

Does anyone know of a way to turn these two keyboard shortcuts (Ctrl-D and Ctrl-Del) off?

Thanks in advance, and my apologies if this actually is in the help file and I just missed it.
