Not only that but if you set your mouse up correctly then you can use the mouse for selections and have it respect window splits too.
That works in tmux too. So you can have use the terminal but have it behave as a GUI app in most respects. For example being able to use a touchpad to quicly enlarge/resize splits or scroll a window can be quite useful.
But apparently according to peer comments, there are ways to yank into clipboards, which is pretty cool.
