今天试了一下你的Prefixless bindings果然好用。

不过，为了和macOS上的iTerm2的绑定兼容:

bind -n M-{ previous-window
bind -n M-} next-window
bind -n M-t new-window -c '#{pane_current_path}'
bind -n M-T new-window
bind -n M-d split-window -h -c '#{pane_current_path}'
bind -n M-D split-window -v -c '#{pane_current_path}'
bind -n M-] select-pane -t :.+ 
bind -n M-[ select-pane -t :.- 
bind -n M-j select-pane -D
bind -n M-k select-pane -U
bind -n M-h select-pane -L
bind -n M-l select-pane -R
bind -n M-J resize-pane -D
bind -n M-K resize-pane -U
bind -n M-H resize-pane -L
bind -n M-L resize-pane -R

所以后来只用这几个:

bind -n M-{ previous-window
bind -n M-} next-window
bind -n M-t new-window -c '#{pane_current_path}'
bind -n M-T new-window
bind -n M-d split-window -h -c '#{pane_current_path}'
bind -n M-D split-window -v -c '#{pane_current_path}'
bind -n M-] select-pane -t :.+ 
bind -n M-[ select-pane -l
