Configure yabai stacks

You're free to bind yabai commands using your favorite key remapper tool (skhd, Karabiner Elements, and even Hammerspoon are all viable options).

That said, you're probably using skhd.

If so, now is a good time to map keys for navigating and manipulating yabai stacks:

# Focus window up/down in stack
ctrl - n : yabai -m window --focus stack.next
ctrl - p : yabai -m window --focus stack.prev

# Add the active window  to the window or stack to the {direction}
# Note that this only works when the active window does *not* already belong to a stack
cmd + ctrl - left  : yabai -m window west --stack $(yabai -m query --windows --window | jq -r '.id')
cmd + ctrl - down  : yabai -m window south --stack $(yabai -m query --windows --window | jq -r '.id')
cmd + ctrl - up    : yabai -m window north --stack $(yabai -m query --windows --window | jq -r '.id')
cmd + ctrl - right : yabai -m window east --stack $(yabai -m query --windows --window | jq -r '.id')
