```
define-command -docstring "vsplit [<commands>]: split tmux vertically" \
vsplit -params .. -command-completion %{
    tmux-terminal-horizontal kak -c %val{session} -e "%arg{@}"
}

define-command -docstring "split [<commands>]: split tmux horizontally" \
split -params .. -command-completion %{
    tmux-terminal-vertical kak -c %val{session} -e "%arg{@}"
}

define-command -docstring "tabnew [<commands>]: create new tmux window" \
tabnew -params .. -command-completion %{
    tmux-terminal-window kak -c %val{session} -e "%arg{@}"
}

```

Then you can map these commands.
