        # This configuration file binds many vi- and vim-like bindings to the
        # appropriate tmux key bindings.  Note that for many key bindings there is no
        # tmux analogue.  This is intended for tmux 1.3, which handles pane selection
        # differently from the previous versions

        # split windows like vim
        # vim's definition of a horizontal/vertical split is reversed from tmux's
        bind s split-window -v
        bind v split-window -h

        # move around panes with hjkl, as one would in vim after pressing ctrl-w
        bind h select-pane -L
        bind j select-pane -D
        bind k select-pane -U
        bind l select-pane -R

        # resize panes like vim
        # feel free to change the "1" to however many lines you want to resize by, only
        # one at a time can be slow
        bind < resize-pane -L 1
        bind > resize-pane -R 1
        bind - resize-pane -D 1
        bind + resize-pane -U 1
