none of the 4 commands in conf file can let tmux goto vi mode
set-window-option -g mode-keys vi
set-option -g status-keys vi
set -g status-keys vi
setw -g mode-keys vi
i write the commands above in the ~/.tmux.conf ,no one can let tmux goto vi mode :
1.press C-b
2.press [
3.use vi key such as movement key : h j k l,but the cursor do not move

the .tmux.conf can let tmux change ,because some bind key can work,but I can not goto vi mode when I want to copy someting
