Time stamp shortcut (Ctrl+D) would be a considerable usability enchantment.

For now, you can use shortcut customization: http://rasm.ods.org/keepnote/manual.shtml#shortcuts

I want to limit the number of default shortcuts that people have to learn. Instead, since different people will use some features more than others, they can each add shortcuts to the features they need. This is why I made customization to easy to do. Thanks for your feedback.

Thanks a lot, I was unable to find custom shortcuts.
