unknown option: mode-mouse with iterm, tmux I've reset my computer and now tmux is complaining about my .tmux.conf having these directives:

setw -g mode-mouse on
set -g mouse-select-pane on
set -g mouse-resize-pane on
set -g mouse-select-window off
set -g default-terminal "screen-256color"


with these errors:

/Users/mdurrant/.tmux.conf:24: unknown option: mode-mouse                  [0/0]
/Users/mdurrant/.tmux.conf:25: unknown option: mouse-select-pane
/Users/mdurrant/.tmux.conf:26: unknown option: mouse-resize-pane
/Users/mdurrant/.tmux.conf:27: unknown option: mouse-select-window


So I have to comment them out, but then my mouse doesn't work in tmux, which is a pain.

How can I enable the mouse in iTerm2 with tmux?

This works on my other Mac.

I use tmux version 2.1.
This looks like a change in tmux in 2.0 -> 2.1

I've replaced

setw -g mode-mouse on
set -g mouse-select-pane on
set -g mouse-resize-pane on
set -g mouse-select-window off


with just

set-option -g mouse on


and everything seems ok
