It follows the UNIX philosophy by doing one thing well (text editing) and interfaces nicely with other CLI tools.

Kakoune first started as a rewrite from scratch of vim, but then ended up being another text editor altogether. So it's inspired in a lot of ways from vim.

Kakoune provides a very expressive set of commands, including various objects selection (paragraph, blocks, words), alignment support, conditional selection filtering...

This set of command is expressive enough to implement all the provided auto indentation logic.

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.

Some keys select, other keys operate on the selections. Shift is used to extend the selection, alt is used for alternative behavior, e.g. reverse the search direction. No inconsistencies like Y which means yy and not y$ in Vim.

A helper pops up when typing commands.
