+  If set to `1`, ALE will show truncated information in the echo line about
+  the symbol at the cursor automatically when the |CursorHold| event is fired.
+  The delay before requesting hover information is based on 'updatetime', as
+  with all |CursorHold| events.
+
+  If there's a problem on the line where the cursor is resting, ALE will not
+  show any hover information.
+
+  See |ale-hover| for more information on hover information.

+  This setting must be set to `1` before ALE is loaded for this behavior
