You can use the mouse to select things in the terminal. In vim/neovim `:set mouse=a` and you can scroll around, select things and move the cursor just like you can in a regular GUI editor.
Now that I know how to enable it for specific modes, I'll definitely be using it for visual mode, and maybe insert mode (we'll see how much that annoys me). Now I'm off to see if I can get the mouse wheel to work at all times but click to place cursor off except when I want it, which would be ideal.
