options with a single foo-style option. For example: set -g status-fg yellow set -g status-bg red set -g status-attr blink Becomes: set -g status-style fg=yellow,bg=red,blink The -a flag to set can be used to add to rather than replace a style. So: set -g status-bg red Becomes: set -ag status-style bg=red Currently this is fully backwards compatible (all *-{fg,bg,attr} options remain) but the plan is to deprecate them over time.
