What is Kakoune?
Kakoune is a code editor heavily inspired by Vim, as such most of its commands are similar to vi’s ones.
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.
Comments and Reviews
Said about Kakoune as an alternative
Similar to Vim but with a consistent and simple editing model that gives instant visual feedback. Self-documenting. Heavily customizable.
