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 you’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 “base” form of the letter, and the second denotes the appropriate embellishment.
