+

+  highlight = true,
+
+  -- How long should above highlight last (in ms)
+  highlight_duration = 250,

+  highlight_group = 'CursorLine',

+  -- Whether to create a visual selection after a movement to a node.
+  -- If true, highlight is disabled and a visual selection is made in
+  -- its place.

+
+  -- Whether to notify via vim.notify in the case of missing parsers
+  parser_notifications = true,

+  -- Whether to notify via vim.notify in the case of incorrect options provided
+  opt_notifications = true,
+
+  -- Whether the plugin adds movements to the jumplist -- true | false | 'left'
+  --  true: All movements more than 1 line are added to the jumplist. This is the default,
+  --        and is meant to cover most use cases. It's modeled on how { and } natively add
