I only see these options in the Data Menu 
I have found this Move items with the keyboard between databases (re-imagined) though
It works alright. I really wish that there was a way to say that I am focusing on processing my inbox. That could open up the possibility for assigning keystrokes to move commands and tags like the old iPhoto keyword window. I’m not getting faster at moving things into DevonThink. I realize that, in time, I won’t be pulling so much in at once but I plan to process enough that I will be at it for months even if I could speed things up.
