My Kakoune config after 2 days of use

kakrc

set global tabstop 2
set global indentwidth 2

# simulate Vim's autochdir
# since we're always running in client mode, since Kakoune doesn't do windows
# https://www.reddit.com/r/kakoune/comments/5dgpze/vimlike_autochdir_option
set global autochdir true
# simulate Vim's expandtab (poorly)
map global insert <tab> '<space><space>'
# simulate Vim's textwidth (but hardcoded to some value)
hook global BufNew .* autowrap-enable

## some Vim-like keybindings

# ctrl-w in insert mode: delete word before cursor
# not exactly like in Vim; when cursor was at end of line, positions cursor *before* preceding delimiter
map global insert <c-w> '<a-;>b<a-;>d'
# ctrl-u in insert mode: delete to start of line
# not exactly like in Vim; when cursor was at end of line, deletes line entirely and you need to hit 'enter' again
map global insert <c-u> '<left><a-;>Gh<a-;>d'
# ctrl-k in insert mode: delete to end of line
# not exactly like in Vim; when cursor was at start of line, deletes character at cursor
map global insert <c-k> '<a-;>Gl<a-;>d<right>'

## replace alt- chords for some important keys

# text object selection
map global user i <a-i>
map global user a <a-a>
map global user x <a-x>
# swap cursor and anchor
map global user ';' '<a-;>'
# join next line
map global user j <a-j>
# repeat last f
map global user . <a-.>
