Can I do with vim bindings 'lh' keys to go one right and then back left from the diff view? somehow I can't have two key bindings with 'h' key

[pczern]

I would like the exit_popup and move_left to both have the h key as this seems for me most natural when going right with 'l' and then back with 'h' in a vim like style. But I can right now only specify one without issues.
