I never bothered to learn that stuff before I started using Vimperator. I tend to prefer buffers over tabs for dealing with multiple files in a single Vim instance, so I never had much use for tab-related keybindings until I started using a vi-like interface for a tabbed browser. Maybe that's just me, though.
