A partir do tmux 2.1 ,
você pode ativar isso adicionando-o ao seu .tmux.conf :
set -g mouse on
Mouse-mode has been rewritten. There's now no longer options for:
- mouse-resize-pane
- mouse-select-pane
- mouse-select-window
- mode-mouse
Instead there is just one option: 'mouse' which turns on mouse support entirely.
Veja a opção mouse-select-pane em man tmux :
mouse-select-pane [on | off]
If on, tmux captures the mouse and when a window is split into multiple panes the mouse may be used to select the current pane. The mouse click is also passed through to the application as normal.
