    bindsym $mod+$down focus down
    bindsym $mod+$up focus up
    bindsym $mod+$right focus right

    ## Layout stuff:

    # You can "split" the current object of your focus with
    # $mod+b or $mod+v, for horizontal and vertical splits
    # respectively.

    ## Scratchpad:

    # Sway has a "scratchpad", which is a bag of holding for windows.
    # You can send windows there and get them back later.

    # Move the currently focused window to the scratchpad
    bindsym $mod+Shift+minus move scratchpad

    # Show the next scratchpad window or hide the focused scratchpad window.
    # If there are multiple scratchpad windows, this command cycles through them.

    ## Resizing containers:

    mode "resize" {
      # left will shrink the containers width
      # right will grow the containers width
      # up will shrink the containers height
      # down will grow the containers height
