Notes in Keyframe Pro 2 allow users to quickly and easily add notes to frames in a source or timeline. Notes can be used for animation review, feedback, quick thoughts, reminders and much more.

Adding/Editing Notes
Add a new note (or edit an existing note) at the current frame by clicking the Add/Edit button 
at the top of the Notes sidebar or by using the Ctrl+W hotkey (Cmd+W on macOS).
This will open the Note Editor window:
After editing the text, click the Save button

to ignore the changes.
A label, applying a colored background to the frame number, can be set by clicking the Label button 
.
