When writing reports it can be helpful to insert newlines in order to make the report more readable, e.g.:

SELECT
  title,
  author
FROM biblo
WHERE
  author LIKE CONCAT('%',<<Author partial name>>,'%')

Trying to do so with suggestions requires a mouse click to close the suggestions window.

Type 'SELECT' and press enter - it just keeps suggesting 'SELECT'
insert a space and it begins suggesting new things and won't clear until you click with the mouse

I would expect something like ESC to clear the suggestions window
