kakoune

Modal code editor with a focus on interactivity

Kakoune is a code editor that implements Vi's "keystrokes as a text editing language" model. As it's also a modal editor, it is somewhat similar to the Vim editor (after which Kakoune was originally inspired). Kakoune can operate in two modes, normal and insertion. In insertion mode, keys are directly inserted into the current buffer. In normal mode, keys are used to manipulate the current selection and to enter insertion mode. Kakoune has a strong focus on interactivity, most commands provide immediate and incremental results, while still being competitive (as in keystroke count) with Vim. Kakoune works on selections, which are oriented, inclusive range of characters, selections have an anchor and a cursor character. Most commands move both of them, except when extending selection where the anchor character stays fixed and the cursor one moves around. See https://vimeo.com/82711574 for a short demo video.
