This sample demonstrates the Notes feature using the shopping cart scenario as an example. When you hover your mouse over the red indicator in the right corner of the cell, any note attached to the cell will be displayed.
The Notes feature allows you to add comments while reviewing a document. You can enable or disable the notes option using the enableNotes property; by default, it's enabled. To insert a note into cells, use the "Add Note" context menu option. Once added, notes can be edited or removed using the "Edit Note" and "Delete Note" context menu options respectively. The following keyboard shortcuts apply to the Notes feature: Shift + F2 - Add a note to the current cell. Esc - Save and close the note.
