Simple Shortcuts while keyboard focus is in the message list

1

It would be nice to have simple shortcuts when the keyboard focus is in the Message List Pane. For example:

N = Next Message
P = Previous Message
R = Reply to the message
A = Reply All to the message
D = Delete message
SPACE = Toggle read status (mark as read/mark as unread)
C = Compose message to recipients in the current email

I am sure there are others, but this would make processing a INBOX type folder much easier and faster, which should be a goal of all email clients.

I would much prefer this kind of single-key shortcut system for message lists than the current Ctrl-combination keys. It would make processing long lists of email a much more efficient process.
