vim keybindings with neo keyboard layout

Generally, I wouldn't change the keybindings. The Vim commands work because by and large they're mnemonics. Just leave them alone and use them where they stand. I see that hjkl aren't so well laid out on that layout but you do seem to have cursor keys behind "Ebene 4" so if that's not too much trouble maybe that'd be ok. (I don't find myself using hjkl much anyway, I usually use other more direct jump movement commands.)
