title: How do I copy scrollable text output in iterm2 with tmux?
body: <p>I'm using tmux on iterm2 (3.0.12). I can generally copy text by holding the 'Option (alt)' key and dragging with mouse.</p>
  
  <p>But, this doesn't work when I need to select and copy text output that is bigger than my window/pane size. That is the text for which I need to scroll to view it. e.g. 500 lines of text log.</p>
