Shortcut to close note / comment

[Andrew Trapp 0]

Hello everyone, really enjoying Nitro PDF. I've got my workflow mostly refined, which primarily consists of reviewing PDF files, and am wondering if anyone has an answer to the following point:

Is there is keyboard shortcut to exit from adding a note / comment? I've tried the usuals such as [esc] key but to no avail. As of now, the only way I see is to navigate my mouse to the upper right corner of the note box, to close it. Other than this one, I have been able to find keyboard shortcuts for most every key function.

Thanks for your thoughts and suggestions!
