Overview

Krabby is a web extension (for Chrome, Firefox and surf) for keyboard-based navigation, inspired by Kakoune.

The main differences with existing extensions are:
multiple selections,
keyboard layout agnostic,
SOV (subject–object–verb) constructs and
simple interaction with external programs.
It is also quite usable with the mouse.

    For example, there is no concept of mode in Krabby, but a system of contexts.
  • Composability.
    Composability is better than extensibility.
    Krabby tries hard to provide features that interact well with each other.
