I just upgraded to Vimperator 3.1. Previously I used customized key bindings with the Passing Through protocol. It seems the new version accomodates them for pasting and copying, but not selecting all. I don't know how to program the new key bindings because Ctrl+V is no longer Pass Through. Is this still possible? If so, how?
Maybe this could help:
