Can't use mouse properly when running vim in tmux

Question

I'm running VIM in tmux,

When I'm try to select a range of texts in VIM, the mouse kept resetting its position, thus I can only select one line (the last line where mouse occurs).

Does anyone know how to solve this?

Answer 1

There are two settings that you need to configure for this to work.

1. In your .vimrc add set mouse=a
2. In your tmux.conf add set -g mode-mouse on

You will then be able to use the mouse to select blocks of text.
