 - An alternative to check if the note is updated correctly, use the `find` command. (See [find](#locating-persons-by-ic-number-find) command)
 On the patient list panel, the list will be filtered to that specific patient; On the patient notes panel, the updated notes of the specific patient will be shown.
 
-- If you'd like to add empty line(s), you can use a ` ` (i.e. a normal space) as the note's contents 1 or more times.
+- If you'd like to add empty line(s), you can add an empty note (i.e. `addnote T0123456A n\` 1 or more times.
 Do note that the person list panel will not display the empty line(s) unless there is a note with other characters before and after the note with just spaces.
 
+- The space characters at the start and end of the note are stripped during the execution of this command. So `addnote T0123456A n\ Diabetes` and `addnote T0123456A n\Diabetes` give the same note of `Diabetes`.
