Is it possible to highlight the status line or somehow visualize that I'm in command mode.
Could I create an extra binding action for c-b
? Any idea?
Yes, it is possible by use of conditional ?client_prefix
.
Here's an example which changes color of the status-left part (usually containing session name) of the status line along with putting PFX literal in front to denote prefix is active.
set -g status-left '#{?client_prefix,#[bg=colour212]PFX.#[bg=colour202]#S,#[fg=white,bg=colour203,bold]#S}'
