  -- Constrains the rate at which output from a child command is
  -- processed and applied to the terminal model.
  -- This acts as a brake in the case of a command spewing a
  -- ton of output and allows for the UI to remain responsive
  -- so that you can hit CTRL-C to interrupt it if desired.
  -- The default value is 400,000 bytes/s.

  -- Constrains the rate at which the multiplexer server will
  -- unilaterally push data to the client.
  -- This helps to avoid saturating the link between the client
  -- and server.
  -- Each time the screen is updated as a result of the child
  -- command outputting data (rather than in response to input
  -- from the client), the server considers whether to push
  -- the result to the client.
  -- That decision is throttled by this configuration value
  -- which has a default value of 10/s

  -- Constrain how often the mux server scans the terminal
  -- model to compute a diff to send to the mux client.

  -- If false, do not try to use a Wayland protocol connection
  -- when starting the gui frontend, and instead use X11.

  -- has no effect on macOS or Windows.

  -- Specifies how often a blinking cursor transitions between visible
  -- and invisible, expressed in milliseconds.
  -- Setting this to 0 disables blinking.
  -- Note that this value is approximate due to the way that the system
  -- event loop schedulers manage timers; non-zero values will be at
  -- least the interval specified with some degree of slop.
  -- It is recommended to avoid blinking cursors when on battery power,
  -- as it is relatively costly to keep re-rendering for the blink!
  cursor_blink_rate = 800,

  -- Specifies the default cursor style.  various escape sequences
  -- can override the default style in different situations (eg:
  -- an editor can change it depending on the mode), but this value
  -- controls how the cursor appears when it is reset to default.
  -- The default is `SteadyBlock`.
  -- Acceptable values are `SteadyBlock`, `BlinkingBlock`,
  -- `SteadyUnderline`, `BlinkingUnderline`, `SteadyBar`,
  -- and `BlinkingBar`.
