i mapped Ctrl-W to one of my mouse buttons and can't navigate the internet now without it now middle click opens tabs, thumb button to close after scrolling down a bit, putting me at the top of the next thing i middle-clicked a few tabs ago refusing to upgrade it until i can find another mouse that will let me bind Ctrl-W to a button without a daemon running (onboard memory only)
