Can I use double click to select and copy in tmux?

Question

I am learning to use tmux, I found when I in a tmux window, double-click to select and copy function did not work any more.

Can I use double-click to select and copy just as in iterm2?

I have googled for some time, but did not find an short and clear answer to this. I have added setw -g mode-mouse on in the tmux configure file already.

Answer 1

I found a way to achieve that: hold the option key when double clicking.
