In Vim, why doesn't my mouse work past the 220th column?

Question

I tend to maximize a terminal to one screen, and vertically split several windows in Vim. Everything works fine for the first few windows on the left, but clicking past abou

Answer 1

This has been fixed in Vim 7.3.632. See :h sgr-mouse. Or just put this in your ~/.vimrc:

set ttymouse=sgr

If you want to be compatible with versions that don't have mouse_sgr compiled in, use:

if has("mouse_sgr")
    set ttymouse=sgr
else
    set ttymouse=xterm2
end

To see if your version of Vim has mouse_sgr, run vim --version from the command-line, or in Vim, enter :version, and look for +mouse_sgr.

If you're using older versions of screen, or terminal emulators that don't support SGR, you may need to upgrade or switch. These settings work with all new versions of screen, tmux, gnome-terminal, PuTTY/KiTTY, iTerm2, and Terminal.app, using TERM=xterm-256color or screen-256color.

Update: If you're using neovim, SGR support is enabled by default.
