Thanks for this, you finally got me to look at the mouse options in vim, which I've always preferred off, as it's extremely annoying when using multiple windows and a click to focus window manager (like explorer, for the most part) when it places me somewhere else.

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.
