The current shortcut cheat sheet is fine. Please do include the ability to have other actions be triggered by a keyboard shortcut too such as "snooze" or have the ability for the user to customize the keyboard shortcuts to their preference for each action or an action that is not given a default shortcut.

Also the mail app should detect events in the inbox better so that hovering over the date and time should just create that event or at least allowing the user to highlight it and right click it to create the event. Right now, can only manually add in events and in the mail app, can only add events from the email if you were sent a specific event invite. But say you had an email suggesting a certain date and time to meet with a colleague, that can easily be detected and turned into an event.

Finally, to improve adding events and making things easier especially from a workflow aspect, natural language detection should be incorporated. Especially now as more people dictate and use voice to text features, creating an event from natural language would be great instead of manually having to click each section of the "create event" pop up.

Keep up the good work and thank you for prioritizing privacy and user safety!
