    Digraphs in VIM

    Vim has a special shorthand for entering characters with diacritical marks. If you need some familiar variant of a Latin alphabet character youโ€™ll be able to input it with the digraph system.

    Digraph input is started in insert or command mode (but not normal mode) by pressing Ctrl-k, then two printable characters in succession.
    The first is often the โ€œbaseโ€ form of the letter, and the second denotes the appropriate embellishment.
