+btnPreviousNextSql
+""""""""""""""""""
+
+Generates two buttons in the form title that link to the previous/next record. Records are selected by a query which
+uses the columns 'id', 'btnPrevious' (optional), 'btnNext' (optional) and 'btnCurrent' (optional). Optional columns can
+be used to style the buttons using the AS _link notation. 'bntCurrent' generates a third button in between the other two.
+E.g. `{{!SELECT id AS id FROM Car}}` or `{{!SELECT id AS id, CONCAT('p:<pageSlug>?form=<form>?r=', id, '|s|b|G:<glyphicon>')
+AS btnPrevious FROM Car}}`.
