    Once notes are in place, whether by recording or using "paint" mode,
    the piano roll provides a sophisticated set of note-editing
    actions.
+   But, before editing, one can turn on
+   \index{note!tooltips}
+   "note tooltips", if desired.
+   The thin unlabelled button next to the horizontal scroll bar toggles
+   this mode.
+   When enable, moving the mouse over a note will show its value, time range
+   in units of B:B:T, and its velocity.
+   This view is quicker than opening up the \textbf{Event Editor}.
+   Onward!
