Easier way to rate and delete?

[gnormal]

Hi, I'm new and read almost the whole manual.
One of the main things i want to do is load lots of new stuff on my clipzip and then review it.  so each file i end up deleting or giving a rating.  doing both of these things via context menu takes at least 5 key presses.  how can i shorten this?  i was hoping that shortcuts would help, but thats not clear to me.

also, i want to review only the files that i have not yet reviewed.  so it would be convenient to be able to select all unrated files from the db for the playlist.  i don't see a way to do this.  alternatively i could tag  everything as 1 to indicate an unrated file, but i don't see a way to do that either (except on the laptop side).

thanks for your suggestions!
