      ## On most desktops, WayVR is able to pick up your keymap via wayland. (Especially when using Fcitx5!)
      ## However, if this does not happen, you might want to set your keymap by hand.
      ## When using a simple layout:
      #default_keymap: us
      #
      ## When defining a layout-variant pair, separate using a dash:
      #default_keymap: us-colemak_dh

      #skybox_texture: ""

      ## User-defined list of custom overlays that should be created.
      ## Each entry must correspond to an XML file at: {theme_path}/gui/{entry}.xml
      #custom_panels:
      # - "test"

      ## The alt_click binding can be used to execute a program of choice
      ## These are not default, but example values.
      #alt_click_down: ["bash", "-c", "echo x"]
      #alt_click_up: ["bash", "-c", "echo y"]

      #  DesktopNotification: Center

      #  IpdChange: Hide

      ## Path to a custom notification sound, relative to `~/.config/wayvr`
      #notification_sound: ""

      ## controls the maximum height of the screen
      #screen_max_height: 1440
