Slap vs Kakoune

Slap supports mouse keybindings even though it works inside the terminal and also through SSH.

Slap features configurable keybindings (Ctrl+S, Ctrl+Z, etc).

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.

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

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.

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.

A helper pops up when typing commands.

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.
