[Evolution] expunge individual messages from inbox

[joe akalabs net]

I'm using evolution for the first time and I'm confused about the work 
flow. Looking at my inbox I want to hit something like ctrl-del to 
immediately permanently delete (expunge?) the selected message. For 
other messages I want to hit just delete and have the message moved to 
trash, which seems to work fine. I cannot figure out the first part. Is 
it possible to expunge individual messages without deleting them first?
