The code below enables contextual alternates and ligatures but disables them on your `cursor-line` so you don't sacrifice "editability".

• { -webkit-font-smoothing: antialiased; -webkit-font-feature-settings: "liga" on, "calt" on; }

atom-text-editor .cursor-line { -webkit-font-feature-settings: "liga" off, "calt" off; }
