For anyone learning the web app, it is useful to see a list of keyboard shortcuts. The keyboard shortcuts are currently on a separate page. It would be very helpful to have this list be one keyclick away.

For anyone learning ANY of the apps, the Smart Add shortcut codes, date format codes, etc., would also be very helpful on the same cheat sheet.

Compare with various Google apps and the "Vimium" extension to Chrome, which let you press "?" to pop up a sheet of shortcut codes and "Esc" to hide it again.
